Book review: From Infinity to Man: The Fundamental Ideas of Kabbalah – The Jerusalem Post
In this ground-breaking book, Eduard Shyfrin shows that the ideas of Jewish mysticism (Kabbalah) resonate with the ideas of 21st century science. From Infinity to Man introduces the reader to basic principles of Jewish mysticism such as the ten sefirot the Divine Attributes of God, the description of God as Ein Sof, absolute perfection, and the idea of Ohr Ein Sof, the unending Divine light. It then discusses basic principles of quantum physics and compares many of the concepts of Kabbalah to those of quantum physics, including the theory of information as discussed in Kabbalah and quantum physics. Additional chapters in the book discuss Creation, Kabbalah and Philosophy, and the Torah and Mathematics. Shyfrin is equally well-versed in Jewish mysticism and physics, and names like Einstein, Heisenberg, and Schrodinger frequently appear alongside Kabbalistic luminaries such as Isaac Luria, Shneur Zalman of Liadi, and the Baal Shem Tov.
From Infinity to Man has enjoyed positive reviews since its publication in January 2019.
Midwest bookreview.com writes that it is exceptionally well written, organized and presentedan extraordinarily thoughtful and thought-provoking read and unreservedly recommended for community, college, and university library Judaic Theology/Philosophy collections in general, and Kabbalah studies supplemental studies lists in particular. It should be noted for the personal reading lists of students, academia, and non-specialist general readers with an interest in the subject
Ben Rothke, of the Jewish Link of NJ writes that This is an interesting book and Shyfrin does his best to show the dynamic between Torah and science. Quantum physics is an absolutely fascinating topic and certainly can be used to better understand the nature of the world we live in. In much of the book, Shyfrin finds corollaries between kabbalistic ideas and tries to map them to the world of physics. In From Infinity to Man, Eduard Shyfrin has written a thought-provoking and most curious work.
The San Diego Jewish World writes, Using information theory and a number of kabbalistic ideas, such as the Sephirot and Tzimtzum, Shyfrin shows the only reasonable conclusion is creation emanated from nothing. Shyfrin even links the arrow of time, our understanding that time can only flow in one direction from past to present to future, and not the other way around, to Kabbalah by demonstrating that terrestrial information mimics divine information, which continually flows in one direction, from the unknowable God, Ein Sof, to the world. Kabbalah has been studied philosophically, theologically, and even mathematically. In From Infinity to Man, Shyfrin examines Kabbalah from a new position, the combined effect of quantum physics and the Theory of Information, and in doing so brings to light a heretofore unstudied perspective.
The London Jewish Chronicle writes that in his book, Shyfrin uses concepts such as information theory to recast kabbalistic insights in scientific terminology. Or as the motto on the cover of the book puts it, In the beginning, God created information

Book review: Travels with Sushi in the Land of the Mind – The Jerusalem Post
Travels with Sushi in the Land of the Mind was published in October 2019 and introduces children to quantum physics and classic morality through a journey to another universe. The book is based on stories that author Eduard Shyfrin has told to his grandchildren, and follows the adventures of young Aaron and Stella, siblings who are transported to the Land of the Mind, a fantasy kingdom based on mathematical principles and quantum physics. The plot parallels numerous stories found in the Bible and is intended for children ages twelve and up.
Throughout the book, Travels with Sushi introduces children to positive values such as hope and courage and helps them deal with fear, indifference, and pride. In Shyfrins view, the best way to teach children morals and good character traits is by wrapping them in an exciting story. We dont know what our children will become, he says. Our duty is to give them some direction in life to give them a wider view of life, to introduce them to ideas of God, of science and knowledge, of good moral qualities, and then they will be better equipped to find their way in life.
Travels with Sushi has enjoyed favorable reviews since its publication, and recently received the Independent Press 2020 Distinguished Favorite award.
Library KSP Blogspot wrote, Travels with Sushi in the Land of the Mind by Eduard Shyfrin was a little like being in The Matrix. While not usually a fan of fantasy, I was drawn into the story. Aaron and Stella enjoy spending summers at their grandparents' house by the seashore (or "Down the Shore," as we say in New Jersey). They play on the beach, and then the family goes to eat at their favorite sushi restaurant, where Mr. and Mrs. Ekaku, a polite Japanese couple, serve the sushi. They come to the table and ask Stella and Aaron, salmon sushi connoisseurs, to try a new delicacy that the chef created. It is the most delicious sushi they have ever tasted: "a thousand flavors seemed to burst from within the tiny golden parcels." They close their eyes to fully focus on enjoying the sushi, and when they open them....they are in the Mushi Land of the Mind, where Salmon Mushi, the lead of the Mushi tribe, enlists their help. They must find the Supreme Ruler's Book in a cave on Memory Mountain and return it to the people, which will destroy the power of the Black Queen.
What is fascinating about this book, besides the journey/quest of the children, is how Jewish elements are interwoven into the story. The Supreme Ruler is, well, the Supreme Ruler, and there are snippets of Jewish history, quotes from the Mishnah and the Talmud, a discussion of the Sefirot, a lesson in Middos, and a certain tribe that "does not eat shrimp sushi."
Adding another layer, are the principles of physics and The Golden Ratio, explained in terms clear and simple enough for young readers. Albert Einstein makes an appearance to help the kids get through a wormhole.
Tomislav Tomic's amazing illustrations made the book that much more enjoyable. The detailed black and white drawings complemented the text perfectly.
If you enjoy fantasy, or if you want to expand your horizons and read something you wouldn't normally read, this is a great choice.
Shilo Musings Blogspot wrote, I have grandchildren who are more talented and knowledgeable about sciences than me, so I had an ulterior motive for taking the book. As soon as I finish writing this book review, I'm going to find a way to pass it to them.
To my great enjoyment and utter surprise, I discovered that Travels with Sushi is much, much more than a children's "science book." It's a fable about the Jewish People, our enemies and the Bible.
Aaron and Stella, the brother-sister pair are the main characters. They love and eat sushi, but they don't eat it with shrimp. Hmm what does that make you think of? This Aaron, like the biblical one, partners up with a sibling. But instead of brother Moses, he works with sister Stella. Could the name Stella come from the biblical Esther? Maybe.
Travels with Sushi includes lots of magic, which should attract the Harry Potter fans. Aaron and Stella end up in a mysterious frightening, dangerous world after eating special sushi. There's a Supreme Ruler and a Book and the "good guys" being attacked; BTW they don't eat shrimp. Aaron and Stella must rescue them before their memories are stolen.
I must say that I truly enjoyed reading Travels with Sushi. For those of us attracted to character and plot, the physics and math don't stand out. It's suitable for older children, precocious younger readers and makes a great book to read to your children, too.
Mario Routi, bestselling author, says, Alice in Wonderland meets Narnia and science! A very clever outstanding page-turning fantasy, with interesting characters and many unexpected surprises. Eduard Shyfrin, with his powerful writing, has managed to combine mysticism and fairy-tale with quantum physics, mathematics and philosophy, in a wonderful atmospheric children story, creating for his readers a brilliant adventurous ride with deeper meanings and insights.
Finally, National Geographic for Kids says,
This was an intriguing book and I found every page a new mystery. I recommend it to older readers for its thrill and excitement and hope you enjoy it as much as I did.

A Brighter Tomorrow > News > USC Dornsife – USC Dornsife College of Letters, Arts and Sciences
From environment to family, transportation to health care, from work and leisure to what well eat and how well age, USC Dornsife faculty share how they think our future world will look. [11 min read]
As the 19th century drew to a close and a new era dawned, an American civil engineer named John Elfreth Watkins consulted experts at the nations greatest institutions of science and learning for their opinions on 29 wide-ranging topics. Watkins, who was also a contributor to the Saturday Evening Post, then wrote an extraordinary magazine article based on what these university professors told him.
Published on Page 8 of the December 1900 issue of Ladies Home Journal a sister publication of the Post it was titled What May Happen in the Next Hundred Years. Watkins opened the article with the words, These prophecies will seem strange, almost impossible. In fact, many of his far-sighted predictions for the year 2000 which included the invention of digital color photography, television and mobile phones proved remarkably accurate.
For this issue of USC Dornsife Magazine, we have repeated the experiment by inviting 10 scholars drawn from USC Dornsife faculty and representing diverse disciplines to predict what the world will look like in the year 2050 and the year 2100.
A Bluer Planet
Astronauts circling the globe in 80 years may find our blue planet looking quite a bit bluer, says Naomi Levine, assistant professor of biological sciences and Earth sciences.
The middle of the Pacific or Atlantic oceans are what we call the deserts of the ocean. Theyre really low in nutrients, and things that live there are usually small. As a result, these areas look very blue because there isnt much ther except water, Levine explains. As the climate warms, we predict that these desert areas are going to expand. So, ocean waters will look bluer from space.
A Brighter Shade of Green
Our planet may also look a bit greener. Travis Williams, professor of chemistry, says that without an active plan for removing the carbon clogging our atmosphere, nature could step in.
If we dont choose a biomass thats going to utilize higher temperatures and that atmospheric carbon, nature is going to choose on our behalf, and I dont think were going to like it, he says. To avoid harmful organism explosions like algae blooms, Williams foresees a human-led reforestation of the planet, at a scale several times the size of the Amazon rainforest.
What's On the Menu?
A greening planet could also be due to changes in our agricultural systems. A move away from monoculture farming and a return to an ancient polyculture approach might be on the horizon, says Sarah Portnoy, associate professor (teaching) of Spanish. Portnoy researches indigenous food cultures of Mesoamerica and suggests that in the future we could adopt the milpa food system. Animals would be grazing on the same land where there are cover crops and squash, corn, beans and all kinds of herbs growing together, she says.
This isnt just a utopian pipe dream. Governments will have to seriously rethink agriculture if they want to reduce rising rates of chronic disease such as obesity, especially among the poor. The agriculture that is supported by the government now is skewed toward crops like soybeans and wheat. Our food system is geared to the cheapest calories, Portnoy says.
The high-calorie, processed foods produced from these monoculture, subsidized crops are less expensive than fruits and vegetables, but do little for our health. Unless we reprioritize which crops get government cash, we can expect disparities in health between economic classes to continue. By 2050, only the privileged might be able to afford strawberries or carrots.
Food supplies will alter in other ways as well, thanks to climate change. The bluer oceans will be less friendly to bigger marine organisms, which means fewer large fish to harvest.
When you change ocean temperatures, it changes what types of organisms can grow, and that cascades up the food web, says Levine. Sushi chefs in 2050 might dish up more avocados and scallops than tuna rolls. This could work for future diners, Portnoy thinks. Theres a move toward being a lot more intrepid as an eater, and toward plant-based diets, she says.
One Big, Happy Family
Starting off your day in 2050 could mean wheeling your toddler to the state-funded neighborhood day care center. Birth rates are currently plummeting across the industrialized world and governments may soon need to tackle the problem as a public health priority, says Darby Saxbe, associate professor of psychology and director of the USC Center for the Changing Family.
Well realize that, when the birth rate goes down, that affects our future workforce, she says. When were not able to replace our population, it ultimately becomes a national security issue. Child care benefits, family leave and subsidized, part-time work schedules for parents could be the governments strategy to encourage a new baby boom.
We may be well into the digital age, but you might not find too many iPads in the nurseries of the future. Increased awareness of the pitfalls of screen time could change our approach to parenting via device. The original scions of social media themselves now admit to limiting their own childrens time online, observes Saxbe. In fact, in some of the more expensive private schools in Los Angeles, you have to sign a no screen time pledge.
The keywords there might be expensive and private. A movement away from childhood spent online could leave behind children from poorer families as technology becomes cheaper and the cost of human labor rises. It will likely soon be less expensive to instruct classrooms of kids via lessons on tablets than by engaging a human teacher.
You might end up with a two-class system, Saxbe warns. You have more kids having a digital childhood thats a little less regulated, especially in neighborhoods where its not safe to play outside. Wealthier families are going to be able to afford more hands-on child care and more hands-on educational activities, instead of leaving kids alone with their technology.
However, technology can still benefit the family in the coming decades. In fact, Saxbe believes this is a largely untapped opportunity with great potential. Silicon Valley technologists primarily childless young men still havent tackled devices like the breast pump or baby monitor, which could both use a redesign.
Has there been a real focus on innovation and investment when it comes to things that serve parents and families yet? asks Saxbe. I think theres a big market there.
Working 10-4
After dropping your child off at day care, you head to work. You likely wont be putting the keys in the ignition of your own car, though. Kyla Thomas, sociologist at the USC Dornsife Center for Economic and Social Research and director of LABarometer, a quarterly internet-based survey of approximately 1,800 L.A. county residents, says that by 2030 commuters will probably rely more on public transit and shared, autonomous vehicles to get around.
Public transportation will be faster and more convenient, and increased density in neighborhoods will mitigate sprawl. Parking will be more expensive and harder to find. By 2100, Thomas says, private car ownership will be a thing of the past.
Hopping out of your driverless commuter van, you clock in at the office for your six-hour work day. Patricia Grabarek, lecturer with USC Dornsifes Online Master of Science in Applied Psychology program, believes that the traditional 40-hour work week could get phased out by 2050.
We are in the midst of a job revolution thats on the scale of the Industrial Revolution, Grabarek says. The entire nature of work will change.
Automation promises to replace many jobs, and streamline others. Combine this with the growing emphasis on work-life balance, embodied by current millennials pushing for workplace flexibility, and we could see our work week lighten in load.
Our leaders are recognizing the problem that employees are burning out. People are working too much and they are not as productive as they could be. Bosses will start modeling better behaviors for their employees, Grabarek says. After-hours emails could soon be banned, as is already the case in France and Germany.
This doesnt mean well all be aimlessly underemployed, however. There is a fear that automation will eliminate jobs but, in the past, weve always replaced the jobs that weve lost. Innovators will come out and replace them with new jobs we cant even come up with now, she says.
No matter how advanced computers become, human curiosity remains superior. Automation will be good at analyzing data, Grabarek says, but the questions will still originate with human researchers.
It's Quitting Time
Finished with work for the week, youre off to start the weekend. One item not likely to be on the agenda? Attending a traditional religious service.
In the United States, theres a trend away from institutionalized religion and toward highly individualized spirituality, says Richard Flory, associate professor (research) of sociology and senior director of research and evaluation at the USC Dornsife Center for Religion and Civic Culture. People just arent interested in institutions anymore, and nothing seems to be stepping forward to replace that interface between the individual and society.
Churches and temples could find new life as condos, bars or community centers, with religion relegated to a decorative background.
Rather than kneeling in prayer, people might find themselves downing a psychedelic drug to reach personal spiritual enlightenment. Movements that center around hallucinogens such as ayahuasca, a psychoactive tea from the Amazon, have gained traction in recent years, Flory notes.
Of course, there might just be an app for it all. Consciousness hacking aims to use science to bypass years of devotion to a spiritual practice and give everyone the hard-won benefits of such a practice instantly. In the future, I could see having some sort of implanted device to get to this level of consciousness, Flory says.
Reading the Tea Leaves
You may also use your leisure time to crack open a good book one with a slightly different texture. As climate change threatens our traditional resources, more sustainable alternatives such as seaweed could step in as a paper substitute, predicts Mark Marino, professor (teaching) of writing and a scholar of digital literature.
By 2100, literature could be written across the heavens instead.
Roboticist poets will create autonomous micro-texts that will be able to swarm into collectives, self-organize, aggregate and adapt, says Marino. Bevies of these nano-rhy-bots will create superstructures that can write epics on the Great Wall of China, on the surface of Mars or in the bloodstream of their readers.
Better Living Through Quantum Computing
Aging in the New Age may mean more nontraditional family units. Older adults prefer to age and die at home, but what happens when you dont have a big family network to support that? It may mean people might be more invested in friend networks, or the idea of chosen family, says Saxbe. Cue The Golden Girls theme song.
Sean Curran, associate professor of gerontology and biological sciences, believes that a focus on increasing our health span, the period of life during which one is free from serious disease, rather than simply elongating our life spans, will improve the quality of our longer lives as we age.
The goal is to have a personalized approach to aging that takes into account an individuals genetics, environment and life history, explains Curran. The assisted living facility of the future will be patient-centered, with each resident having a personalized prescription to maintain optimal health.
Eli Levenson-Falk, assistant professor of physics and astronomy, predicts that quantum computing could unlock the development of those drugs.
Quantum computers solve problems much more swiftly and with higher information density than todays computers. Although the technology is still in its infancy, Levenson-Falk predicts that by 2050, practical quantum technologies will be used commercially by major drug companies for research and development.
Enormously complicated computational tasks like simulating a chemicals molecular structure are much more achievable through this technology.
The idea is that with a quantum computer you can sort of emulate nature, he explains. We might have the canonical example for this by 2050: the physical shape of a protein molecule.
Predicting this shape is nearly impossible with a classical computer, Levenson-Falk says.
Measuring it is difficult and requires you to predict the shape first. With a good quantum simulator, we can emulate the protein and just let quantum mechanics do the processing for us, then measure the result at the end.
The Quantum Age
Indeed, quantum computing might solve questions that relate to the very fabric of the universe. Or at least get us closer to the answers.
Dark energy, dark matter, quantum gravity and thequantum classical transition are the principle problems existing in physics today. Quantum technologies are the best bet to solve the last one, says Levenson-Falk. Quantum sensors will probably also be used to help detect dark matter, or at least falsify some theories. And there are some proposals for using quantum technologies to poke at quantum gravity.
We cannot, of course, predict our shared future with 100 percent accuracy, but one thing we can be sure of is that it will be filled with new challenges and opportunities to create a better tomorrow. Although advances in technology will certainly help determine our future, how equitably those advances are shared in our interconnected world will also play a dominant role in shaping it.
This is a tale of two societies: You could either see things get better and more supportive for families, or you might see two-class stratification, Saxbe warns.
As the future unspools, we are given both the invaluable gift and the tremendous responsibility of deciding how we want it to look. Whether our world in 2100 takes on the dystopian qualities of Blade Runner or embodies the utopian, egalitarian ideals of Star Trek remains in the terrestrial hands of those already building that future.

The logic of the impossible: Moses our rabbi – The Jerusalem Post
Let us recall how the story of the Exodus begins.
The Almighty addressed Moses from a burning bush, and entrusted him with a mission to go to Pharaoh and take the Jewish people out of Egypt. Moses, who had a brilliant intellect, spoke logically with the Almighty about the conditions that he believed would ensure the mission's success:
1) Moses asks, Who am I? (In what capacity do I go?) and the Almighty replies that I will be with you (Shemot, 3:11-12).
2) Moses asks God to tell him His name, in order to understand the capacity in which God reveals Himself to the Jewish people. God reponds by revealing to Moses some of the secrets of the divine name (Shemot, 3:13-15).
3) Moses asks what to do if the Jews do not believe him, and God grants him the ability to performs miraculous signs (Shemot, 4:1-9).
4) Moses tells the Almighty that he does not have the gift of eloquence. God responds: Who gave man a mouth, or who makes [one] dumb or deaf or seeing or blind? Is it not I, the Lord? So now, go! I will be with your mouth, and I will instruct you what to speak. (Shemot, 4:10-12).
5) But this answer does not satisfy Moses and he says, I beseech You, O Lord, send now with whom You would send. The Almighty tells Moses that his brother Aaron will speak for him (Shemot, 4:13-16).
After this conversation, Moses believes that all the conditions for success have been specified, and he sets out for Egypt.
Moses and Aaron went to the Jewish people, performed miraculous signs for them, and told them the joyful news of deliverance. The Jews believed them. After that, Moses and Aaron went to Pharaoh and delivered the edict from the Almighty to release the Jews. And then something incredible happened: the Pharaoh not only refused to release the Jews, but also made their life and work much worse and more difficult. But that was not the end of the story. The Jews accused Moses and Aaron of being imposters. They said, May the Lord look upon you and judge, for you have made us a foul odor in the Pharaohs eyes. (Shemot, 5:21) This seems to imply the Jews did not believe that Moses and Aaron were messengers for the Almighty. For Moses, who infinitely loved the Jewish people, this meant the complete failure of the mission and a personal disaster. Let us try to logically follow the course of his thoughts.
Moses had already been informed by God that the Pharaoh would not immediately let the Jews out of Egypt, and that he will do so only after great punishments would be inflicted on the Egyptians (Shemot 3:19-20). So he expected that punishments would follow after Pharaohs refusal, which would lead to the Jews deliverance. But when instead of releasing the Jews from Egypt Pharaoh made their lives more difficult, there was no punishment.
The logic of Moses's reasoning can be imagined as follows.
1. The Almighty is all-powerful and always speaks the truth.
2. Therefore, the Pharaoh should have immediately been punished after refusing to release the Jews and, after that, should have let them go.
3. However, the opposite happened.
One of the main tasks of logic is to determine how to reach a conclusion from the prerequisites and obtain true knowledge about the subject of deliberation.
One of the most frequently practiced types of proofs in classical logic is proof by contradiction (ad absurdum). The principle is this: if the conclusion obtained from the prerequisite contradicts reality, then the prerequisite is not true.
From the point of view of classical logic, point 3 refutes point 1. But for Moses, the omnipotence and truth of the Almighty were indisputable. As a result Moses system of logical reasoning crumbles, he experiences a state of moral collapse, and he cannot continue the mission in such a state. He decides to confront the Almighty: O Lord! Why have You harmed this people? Why have You sent me? Since I have come to the Pharaoh to speak in Your name, he has harmed this people, and You have not saved Your people. (Shemot, 5:22-23).
How does God respond? He says: Now you will see what I will do to the Pharaoh, for with a mighty hand he will send them out..." (Shemot, 6:1).
Apparently, the answer does not satisfy Moses, as it says what will happen in the future but does not explain the events that have already occurred. But there is more to come in Gods response. Reading further,we encounter the following statement:
God (Elohim) spoke to Moses, and He said to him, I am YHWH. I appeared to Abraham, to Yitzhak, and to Jacob with [the name] Almighty God (El Shaddai), but [with] My name YHWH, I did not become known to them. (Shemot 6:2-3)
This passage from the Torah has been the subject of numerous comments. Let us briefly consider the main ones.
Rashi (based on the Midrash) believes that there is a reproach in the words of the Almighty, You have doubted My ways, unlike Abraham to whom I said, ...For in Yitzhak shall you have posterity, (Bereshit, 17:19) and then said, Bring him up there for a burnt offering (Bereshit, 22:2), and he did not doubt Me (although the first clearly contradicted the second). Rashi sees the words I am YHWH as carrying the message, I am faithful to My promises and I can be relied upon.
Abraham Ibn Ezra, commenting on the Moses question to the Almighty, writes: Moses believed, from the very first time he came to Pharaoh, that it would become easier for the Jews, but it became harder for them. Ibn Ezra comments on the words I am YHWH as follows: This means that My name 'God Almighty' (El Shaddai) became known through the forefathers, and through you My glorious name YHWH will be known all over the world.
According to Nachmanides, the Almighty tells Moses that the Patriarchs did not see Him through the transparent glass as Moses sees Him.
The Lubavitcher Rebbe, commenting on Torah passage, explains that Moses served the Almighty mainly through intellect, whereas the Patriarchs did so mainly through emotions. Therefore, Moses question was not wrong. The inability to understand the actions of the Almighty weakened Moses' intellectual connection with Him. Therefore, Moses question was not a challenge, but rather an attempt to approach the Almighty. Rebbe explains the Almightys response as follows: Do not serve Me with intellect alone. Balance your intellect with emotion and faith, so that you can serve Me without any restrictions.
Fully agreeing with the previous commentaries, the author proposes the following additions.
Carefully reading the Torah, we can see how the character and mental qualities of the main figures constantly change in the context of events and their communications with the Almighty. The Almighty not only punishes and rewards, but also, with His every action and word, He teaches the main characters lessons, raising them to higher and higher spiritual levels.
In the Torah we read: God (Elohim) spoke to Moses, and He said to him, I am YHWH There is a full stop after these words. This sentence contains a complete thought. From my point of view, the words I am YHWH are the main message of the Torah .It is not necessary to see this as a rebuke to Moses, and I offer the following understanding of these words of the Torah. In my opinion, the Almighty was saying to Moses:
Your question is correct according the logic of the world around you, which is the external manifestation of My name Elohim. The Patriarchs lived according to this logic; that was their mission. Pharaoh also lives according to this logic.
But I am YHWH, and from now on, the Jewish people and the world will live according to other laws. From this point on, all events will occur according to My logic as YHWH), the logic hidden deeply within My name God (Elohim), the logic of the impossible, the logic of the highest sefirah (divine attribute), Chochmah (wisdom).
According to the 'external' logic of Elohim, the Jews will never leave Egypt, and according to the hidden logic of YHWH, they will come out. And many years later, when a small Jewish people will be dispersed among large and powerful nations, according to the external logic of Elohim, the Jews would have to disappear; according to the logic of YHWH, they will never disappear.
You, Moses, are chosen to rise to the level of my hidden logic of YHWH, to the level of the highest Chochmah, and from this level to bring the Torah to the Jewish people. And for as long as the Jewish people will be with the Torah, the external logic of Elohim, the logic that rules the natural world, will not have power over them.
Abraham Ibn Ezra, who wrote books on astrology, wrote in his commentary on the third chapter of Shemot on the phrase I am the YHWH: The human soul is above the middle world and, therefore, if a person is wise and has known the acts of the Almighty, performed with and without intermediaries, has retired from the passions of this world to cleave to the Glorious name, even if a persons horoscope predicts trouble on a certain day, the Almighty, to Whom the person has cleaved, arranges events so that he will escape from trouble.
It is also necessary to answer the question of how to understand the presence of the hidden logic of YHWH within the name Elohim. This issue has been discussed in great detail in a Hasidic discourse by the Rebbe Rashab (the Fifth Lubavitcher Rebbe) titled VeYadaata, which comments on the phrase from the Torah You must know that YHWH is Elohim).
Here is a brief explanation. The main thesis of the Kabbalah is that in discussing the Almighty in the category of Ein Sof (the infinite), which is inaccessible to our understanding, the existence of creations with their own "self" is impossible. Therefore, at the beginning of creation, the Almighty produced a tzimtzum process, which is allegorically described as the creation of some empty space with the subsequent emission of a beam of light (kav) from which the whole creation originated. This process should be understood not as the creation of some physically empty space, but as the concealment by the Almighty of His infinite light (information) and the radiation of the finite light from which the whole creation originated.
This finite ray of light carried the information of all of creation. In passing through the chains of the worlds, the light (information) was concealed in such a way that in our world we barely see the Divinity. However, it should be understood that information does not disappear anywhere when something is concealed it does not cease to exist. And under certain circumstances, concealed information can be obtained.
Let us give a simple example: If we look at a stone lying on the ground, we immediately obtain information about its color and shape. In fact, however, the information we receive is an insignificant part of all the information contained in the stone. Employing certain methods, we can obtain information about the chemical composition of the stone, its atoms and molecules, electrons, neutrons and protons, etc.
Similarly, reading the Torah simply as a story, we obtain an insignificant amount of information. However, pondering the words of the Torah, analyzing them, finding hidden connections, fulfilling the commandments, we can, step by step, approach a comprehension of the information hidden in the Torah, and thus approach the level of YHWH.
The Patriarchs
Now, let us turn to the second part of Gods communication to Moses: I appeared to Abraham, to Yitzhak, and to Jacob with [the name] Almighty God (El Shaddai), but [with] My name YHWH, I did not become known to them.
In the section Lech Lecha of the book of Bereshit, we read:
And He said to him, I am YHWH, Who brought you forth from Ur of the Chaldees, to give you this land to inherit it.
The phrase is similar to the one spoken to Moses. But Abraham asked the question, O Lord God (Adonai YHWH), how will I know that I will inherit it? (Bereshit, 15:7-8). In response, the Almighty told Abraham about the future enslavement of the Jews in Egypt and their exodus (Bereshit, 15:13-14).
Some of the commentaries believe that the Jews exile and slavery in Egypt was in punishment for Abrahams question. I do not share this opinion. In my view, Abraham could not be faulted for asking the question, as he was not aware of the logic of YHWH the logic of the impossible. According to the logic of the world around him, it was incomprehensible that he, and the 318 people who were with him, would inherit a land populated by numerous and powerful nations. However, it is an obvious fact that for the rest of his life, Abraham lived with the thought that his descendants would be slaves.
Similarly, when the Almighty tells Abraham that He will give him a son from Sarah, we read in the Torah: Then Abraham fell upon his face, and laughed (va-yitzhak, in the Hebrew). And he said to himself, Will [a child] be born to one who is a hundred years old, and will Sarah, who is ninety years old, give birth? The Almighty heard what Abraham said to himself, and said to him, You shall name him Yitzhak (will laugh) (Bereshit, 17:17, 17:19). Subsequently, when Sarah hears about the future birth of her son, she also laughs, and the Almighty reproaches her for this (Bereshit, 18:12-15).
It is paradoxical that Yitzhak, whose names means will laugh, embodied the quality of Gevurah (constriction, severity, judgment), and, apparently, he rarely laughed. Nor was it a laughing matter for Abraham and Sarah when the Almighty ordered Yitzhak to be sacrificed.
However, after Abrahams circumcision, and the subsequent miraculous birth of Yitzhak, everything changes. Abraham no longer asked the Lord questions, and even when the Almighty ordered him to sacrifice Yitzhak, despite the fact that He promised Abraham offspring from him, Abraham did not ask God questions the lesson had been learned. From this fact, we can conclude that after his circumcision and the miraculous birth of Yitzhak, Abraham was at a much higher spiritual level than he was before. He had begun to recognize the Almighty as He operates with the name of YHWH, with the logic of the impossible.
Pharaoh
Let us now return to the events of the Exodus. When Moses and Aaron came to Pharaoh for the first time, they said:
So said the Lord God (YHWH Elohim) of Israel, Let My people go, and let them sacrifice to Me in the desert. And Pharaoh said, Who is YHWH that I should heed His voice and let Israel go? I do not know YHWH, neither will I let Israel go. (Shemot 5:1-2)
We note that Pharaoh did not say, I do not know God (Elohim), from which it can be concluded that Pharaoh also lived within the logic of Elohim. But this can also be proved in another way.
During our conversation, the Chief Rabbi of Russia, Berel Lazar, drew attention to the fact that after the sixth plague (boils), the Almighty ordered Moses to tell Pharaoh:
So said the Lord God (YHWH Elohim) of the Hebrews, Let My people go so that they may worship Me. Because this time, I am sending all of My plagues into your heart and into your servants and into your people, in order that you may know that there is none like Me in the entire earth. (Shemot, 9:13-14)
Rabbi Lazar raised the question why were these words said after the sixth plague, and not after any other? In order to answer this question, let us note that the first six plagues did not have any long-term consequences, but the plagues that followed this phrase had long-term (locust, hail) or irreversible (death of the firstborn) consequences.
In order to understand why this happened specifically after the first six plagues, let's analyze Pharaohs behavior. From the text of the Torah, we know that the Pharaohs reaction to the plagues came in two forms:
Pharaoh was unrepentant.
Pharaoh repented, but then changed his mind.
During the first four plagues, Pharaohs behavior is repeated as follows:
did not repent repented did not repent repented
Further on, Pharaohs behavior changes. For two plagues in a row (fifth and sixth), he no longer repents.
It is after the sixth plague that the Almighty orders Moses to utter the aforementioned words on His behalf, and during the four subsequent plagues following these words, Pharaoh repents after each plague.
Pharaoh's actions can be explained as follows. Having tried the same sequence of actions for four plagues (did not repent repented did not repent repented), Pharaoh decided for himself that repentance didn't change anything, because in both the case of repentance and in its absence, the plagues were temporary and stopped by themselves. Pharaoh concluded that repentance made no sense, since the plagues stopped on their own accord. And, starting with the fifth plague, Pharaoh changed his style of behavior and, for the next two plagues in a row (the fifth and sixth), he did not repent.
At this point, we can say, that Pharaoh thought that he understood and estimated the logic of Elohim. The moment that he decided this, the Almighty commanded Moses to convey to Pharaoh the message of this time. Gods words can be interpreted as follows: You thought that you figured out My logic? You said that you don't know who YHWH is? Now, you will discover who YHWH is, and see that the logic of Elohim is no longer operable. Instead, you will now be confronted with the logic of YHWH, the logic of the impossible. And now you will repent to the end. And this is what happened.
The logic of the impossible
At this point we should ask: What is the logic of the impossible?
Modern science gives us distant analogies. For example, the logic of quantum mechanics is fundamentally different from the logic of the world around us. In classical physics, if we measure the speed and coordinates of a tennis ball in flight, the result does not depend on the order of measurement. In quantum physics, if we measure the moment first and then the coordinates, or measure the coordinates first and then the moment, the results will be different.
The same thing happens with Aristotles famous Law of the Excluded Middle, which reads as follows: at a point in time, something can be either A or non-A. In quantum physics, we cannot make a similar statement: either a particle or not a particle. Also, many principles of classical logic, such as commutativity, are not applicable to quantum mechanics.
This example illustrates that there is logic that differs from classical logic, which corresponds to our common sense.
As science develops, we will obviously discover other types of non-classical logic.
However, it is fundamentally important to understand that the logic of YHWH the logic of the impossible is not (God forbid) a pattern of non-classical logic.
This last statement needs clarification.
According to the theory of Alter Rebbe, the soul of man was created in the image of the higher spiritual worlds. The soul has garments in the form of an equivalent of the Sefirot Chochmah, Binah, and so on. The soul is an open system. On the one hand, it receives information from the world around us, while on the other hand, it is connected with the higher sefirot of the spiritual worlds.
Our perception of the world, which we can articulate and formulate in the form of reasoning (the system of thinking), unfolds at the level of Binah (understanding). Binah, in turn, receives information from Chochmah(wisdom), which receives information from our world through Malchut (the sefirah that incorporates speech and action), as well as from the higher Sefira Hokma.
It is important to note the following fundamental points:
The information of Chochmahis not articulated and is not recognized by us through the system of thinking (read more in Sefer Yetzirah with comments by Aryeh Kaplan).
Binah reveals some of the information of Chochmah through the system of thinking. The quantity and quality of information disclosed depends on the level of our intellect.
However, even with the most brilliant development of the intellect, all of the information of Chochmah cannot be revealed.
The Torah is given by the Almighty from the highest Chochmah. Consequently, in the Torah, as in the sefirah of Chochmah, there is information that cannot be disclosed at the level of Binah.
This incomprehensible information contains the logic of the impossible, the logic of the highest Chochmah.
This is the logic that lies forever beyond our comprehension, which can be brought to action by faith, trust in the Almighty and a desire for knowledge of the Almighty.

Quantum physics used to physically move objects – IT-Online
For the first time, a team led by researchers at MIT LIGO Laboratory has measured the effects of quantum fluctuations on objects at the human scale.
In a paper published in Nature, the researchers report observing that quantum fluctuations, tiny as they may be, can nonetheless kick an object as large as the 40kg mirrors of the US National Science Foundations Laser Interferometer Gravitational-wave Observatory (LIGO), causing them to move by a tiny degree, which the team was able to measure.
The universe, as seen through the lens of quantum mechanics, is a noisy, crackling space where particles blink constantly in and out of existence, creating a background of quantum noise whose effects are normally far too subtle to detect in everyday objects.
It turns out the quantum noise in LIGOs detectors is enough to move the large mirrors by 10-20 meters a displacement that was predicted by quantum mechanics for an object of this size, but that had never before been measured.
A hydrogen atom is 10-10 meters, so this displacement of the mirrors is to a hydrogen atom what a hydrogen atom is to us and we measured that, says Lee McCuller, a research scientist at MITs Kavli Institute for Astrophysics and Space Research.
The researchers used a special instrument that they designed, called a quantum squeezer, to manipulate the detectors quantum noise and reduce its kicks to the mirrors, in a way that could ultimately improve LIGOs sensitivity in detecting gravitational waves, explains Haocun Yu, a physics graduate student at MIT.
Whats special about this experiment is weve seen quantum effects on something as large as a human, says Nergis Mavalvala, the Marble Professor and associate head of the physics department at MIT. We too, every nanosecond of our existence, are being kicked around, buffeted by these quantum fluctuations.
Its just that the jitter of our existence, our thermal energy, is too large for these quantum vacuum fluctuations to affect our motion measurably.
With LIGOs mirrors, weve done all this work to isolate them from thermally driven motion and other forces, so that they are now still enough to be kicked around by quantum fluctuations and this spooky popcorn of the universe.
Yu, Mavalvala, and McCuller are co-authors of the new paper, along with graduate student Maggie Tse and Principal Research Scientist Lisa Barsotti at MIT, along with other members of the LIGO Scientific Collaboration.
LIGO is designed to detect gravitational waves arriving at the Earth from cataclysmic sources millions to billions of light years away.
The research was funded, in part, by the National Science Foundation.

The Coriolis Effect, Earth’s Spin, and Its Consequences – The Great Courses Daily News
By Don Lincoln, Ph.D., University of Notre DameEarths rotation is realized in movements if they are large enough. (Image: 3d_and_photo/Shutterstock)
The Coriolis effect is realized in how Earths rotation affects the direction of objects flying long distances. An example can help us understand the Coriolis effect best. If there existed a bow and arrow big enough to shoot across the globe, one could stand around the equator and shoot it northward, aiming to hit the north pole. If the arrow was shot from Texas and traveled in a line of constant longitude, youd imagine that it would fly over Oklahoma, Nebraska, South Dakota, North Dakota, and on into Canada. However, in reality, this does not happen.
In reality, the arrow would probably fly over New York State and eventually land somewhere in the Atlantic Ocean. The arrow is deflected rightward to the east due to the earths Coriolis effect the force that does not obey falling and throwing rules in physics.

In 1651, the Italian scientist Giovanni Battista Riccioli realized that the Earths rotation would make a cannonball shot northward deflect towards the east. However, the final name of the effect came from the French physicist Gaspard-Gustave de Coriolis. He published a paper in 1835 about the forces on the rotating parts of industrial machines, particularly water wheels. It took until 1920 for the modern name to become common, but it did. Now it is called the Coriolis effect.
This is a transcript from the video series Understanding the Misconceptions of Science. Watch it now, on The Great Courses Plus.
By using some simple physicsequations, the rotation speed of the Earth can be calculated. The circumferenceof the Earth at the equator is about 25,000 miles. Besides, the Earth rotatesonce every 24 hours to make a full rotation. Consequently, the Earth at theequator is moving at around 1042 miles per hour.
An object four feet away from theNorth Pole travels only a circle of around 24 feet in circumference. The speedin the middle of the northern hemisphere, i.e., around Minneapolis andMinnesota, is a little more than 700 miles per hour. The same speeds apply forthe southern hemisphere. Due to the rotation direction, everything moving fromthe equator to the poles moves eastward: rightward in the northern hemisphereand leftward in the southern one. The air is also something flowing around theEarth.

Hurricanes are a result of theCoriolis effect. Thus, they rotate counterclockwise in the Northern Hemisphereand clockwise in the Southern Hemisphere. Regardless of the air pressure indifferent areas, air flows into the center and is deflected rightward. Withinthe hurricane, the rotating air also wants to deflect to the right. Hence, thehurricane finds a size limit due to air resistance to new incoming air.
There is a constant tensionbetween the pressure differential, making the air flow inward. The outwardpressure is also due to the Coriolis effect. The air pressure difference regulatesthe velocity of the winds. Further, the strength of the Coriolis force isproportional to wind speed, and this interplay sets a limit on the size of thehurricane. As the Coriolis effect is very weak at the equator, no hurricaneshappen there. What else realizes the effect?
Even though some people believethe water in the toilet rotates proportionate to the Coriolis effect, it is toosmall a movement to show it. The water does rotate different directions in thenorthern and southern hemispheres, but that is due to the different directionsof the jets. What can show the effect is the Foucault pendulum, invented in 1851by the French physicist Lon Foucault.
It is made of a very heavy weighthanging from a long cable, moving back and forth like other pendulums. Thedifference is that due to its size, the change in its oscillation direction canalso be seen.
Conclusively, the Earths rotationis the reason hurricanes happen, and it can deviate other flying objects fromtheir path as well.
Learn more about Untangling What Quantum Mechanics Means.
Earths rotation is the main reason for the Coriolis effect. The effect deflects anything that flies or flows over a long distance above the ground, proportionate to Earths spin direction. Even storms can be a result of the rotation; hence, they do not form similarly everywhere on Earth.
The Coriolis effect refers to how a moving object shifts direction rightward in the Northern hemisphere and leftward in the Southern hemisphere. This is the reason hurricane winds turn left in the Northern hemisphere. The effect can be seen in large-scale movements.
The Coriolis effect is the result of Earths counterclockwise spin around its axis. Thus, it is strongest at the Earths poles. The further one moves away from the poles; the lower becomes the Coriolis effect. The effect pushes flying or flowing objects eastward in both hemispheres, but the direction is different in each, depending on the objects destination location.
Even though the water in toilets spins different directions in the northern and southern hemispheres, it is not a result of the Coriolis effect. To see the effect, one needs a much bigger scale, such as hurricanes. The reason water rotates different directions in northern and southern hemispheres when flushing, is the different direction of the jets. The Coriolis effect does exist, but it is too small to see on such a small scale.

Quantum Computing gains as it kicks off commercialization phase with its Mukai quantum computing software – Proactive Investors USA & Canada
Set up at the beginning of 2018, Quantum bills itself as the first publicly traded pure-play quantum computing company
QuantumComputing Inc (), an advanced technology company developing quantum-ready applications and tools,said Wednesday that it is set to gain as it has entered the key commercialization phase as the only public pure-play in the quantum computing space.
The Leesburg, Virginia-based company has kicked off the official commercial launch of its Mukai quantum computing software execution platform. Last week, the company introduced a new trial access program that demonstrates Mukais power to solve real-world problems.
Quantums stock recently traded 1.3%higher to $3.91 a share inNew York.
READ:Quantum Computing launches free trial of Mukai quantum computing application platform
According to the company, the trial will enable developers to discover how they can migrate their existing applications to quantum-ready solutions and realize superior performance even when running their solutions on classical Intel or AMD processor-based computers.
The trial is designed to encourage and facilitate quantum application development to solve real world problems at breakthrough speed and not tomorrow, but today, the company said in a statement.
There are only a handful of quantum software experts in the world, and fortunately for us, this includes Mike and Steve," commented Quantum CEO Robert Liscouski. They have been doing an outstanding job building out our software engineering teams, developing our first quantum-ready products, and preparing QCI for commercial success.
Quantum kicked off 2020 with the public release of its first quantum-ready software product, the QCI Quantum Asset Allocator (QAA). This solution is designed to help portfolio managers maximize returns by calculating their optimal asset allocations, said the company.
QAA is the first of a series of Quantum products that will leverage quantum techniques to provide differentiated performance on both classical computers and on a variety of early-stage quantum computers, added the company. Naturally, Quantum is looking to convert its QAA beta users into long-term customers.
The core of our strategy has been to anticipate the direction of the market and be ahead of it by offering unique solutions that establish QCI as a market leader, said Liscouski. We will be driven by the market, but in turn will drive the market by helping our customers realize their quantum-enabled future.
The company said that while quantum computing is typically a high-dollar investment given the "sophisticated and costly hardware," Mukai makes quantum application development affordable and scalable compared to running solutions on intermediate quantum computers, like those offered by D-Wave, Fujitsu, IBM and Rigetti.
Mukai addresses the quantum computing market which is tipped to grow at a 23.2% compound annual growth rate to $9.1 billion by 2030, according to Tractica.

Is quantum computing ready to leap into the real world? – ARNnet
Market research firm IDC predicts that by 2023, 25% of Fortune 500 companies will gain a competitive advantage from quantum computing.
Its a bold prediction given the current dearth of real-world examples of quantum computing in action. However, theres plenty of industry activity to back up IDCs forecast. In fact, early this year at the Consumer Electronics Show the biggest buzz wasnt the newest smartphone, wearable device or autonomous-driving technology, but rather unprecedented computing power based on an area of quantum physics Albert Einstein described as "spooky action at a distance."
While quantum computing hasnt yet factored into solving worldwide problems such as the coronavirus pandemic, that is exactly the type of problem quantum has the potential to address. That potential will turn into a reality, according IBM, one of a handful of tech giants leading the quantum charge. This is the decade that quantum computing gets real, says Katie Pizzolato, director at IBM QStart.
For that reason, Pizzolato said, it was important to keep quantum public-facing rather than keep it a technology buried in research facilities. We wanted to get quantum out of the labs and into the real world, she said in reference to IBMs strong presence at CES.
Companies such as Google, Microsoft, D-Wave and Regetti are also eager to move quantum forward, and based on IDCs recent report Quantum Computing Adoption Trends: 2020 Survey Findings, the technology is building momentum.
According to responses from 520 IT and line-of-business professionals, quantum computing budgets and implementations will increase in the next 18-24 months. Half of all respondents to the IDC survey reported that funds allocated for quantum computing accounted for just 0-2% of the annual IT infrastructure in 2019, but will account for 7-10% in the next 24 months. For companies with more than 10,000 employees, the spending increase is more dramatic more than half of respondents will spend between 9% and 14% on quantum technology over the next two years.
Respondents to the IDC survey were clear where they are focusing their attention: 65% of respondents are using to plan to use cloud-based quantum computing, followed by 45% who use or plan to use quantum algorithms (which includes simulators, optimizations, artificial intelligence, machine learning and deep learning). Quantum networks (44%), hybrid quantum computing (40%) and quantum cryptography (33%) round the top five, according to the IDC survey.
Heather West, IDC senior research analyst, Infrastructure Systems, Platforms and Technology and one of the reports authors, says that quantum computing excels at solving large problems where theres so much data. The initial areas of focus will be AI, business intelligence and overall productivity and efficiency, according to the IDC report.
Very few companies have actually operationalized [quantum computing]. The skillsets are so advanced, and few people really understand quantum, West said, adding that were still at the experimentation stage with algorithms as companies also look to overcome challenges such as cost, security and data transfers between vendors. West points out, however, that there are already practical use cases in areas such as manufacturing and finance.
Right now, West says, the focus is on how to optimize processes. However, in the future, quantum will be applied to larger problems such as how to address climate change and cure diseases.
As IDCs West says, quantum computing isnt without its challenges. IDC cites complex technology, skillset limitations, a lack of available resources, cost, security, data transfer among vendors as barriers to adoption. With so many challenges, its not surprising that when selecting vendors to support quantum technology initiatives big names dominate the responses in the IDC survey. Google tops the list with 37% of respondents citing it as the vendor of choice, followed by Microsoft with 32%, IBM with 27% and Intel with 23&.
What makes quantum computing more powerful than classical computing is that rather relying on binary bits (i.e, either a 1 or 0) quantum computing uses qubits. Qubits can process more data because they can exist in many possible combinations of 1 and 0 simultaneously, known as superposition, processing an enormous number of outcomes.
In addition to superposition, pairs of qubits can be "entangled." This entanglement is what makes quantum computers as powerful as they are. What make it even more intriguing is that no one knows how or why it works, prompting that spooky action description from Einstein.
In classical computing, doubling the amount of bits gives you, as youd expect, twice the computing power. However, thanks to entanglement adding more qubits gives you exponentially more processing power.
If processing power potential is the good news on qubits, their fragile nature is the bad news. Not all qubits are created equal, IBMs Pizzolato says. Qubits are unpredictable and susceptible to environmental noise and errors. After an error they fall back to a binary state of 1 or 0, so the longer the calculation runs without an error, the greater the calculation. The goal is to protect against errors to solve the most challenging problems, Pizzolato says.
How common are these errors? A slight fluctuation in temperature or vibration can cause whats known as "decoherence." And, once a qubit is in decoherence, its calculation has failed and must be run again. For that reason, quantum computers are housed in environments of near absolute zero and with little outside disruption.
More qubits help. The 50 qubits range is when you start to supersede what you can achieve on a supercomputer, says Pizzolato. IBM last fall announced its 14th quantum computer, a 53-qubit system. Its previous quantum computers were 20 qubits. However, quantum is more than qubits. Hardware is at the center of the circle, but then you have the algorithms and the applications, says Pizzolato. More sophisticated algorithms are critical to quantum computings real-world success. Quantum is all about the algorithms you can run and the complexity of those algorithms, she says.
Skills gaps are a challenge for IT in general. With quantum computing, its magnified. Where will the quantum development come from? Peter Rutten, research director and one of the authors of the IDC report, says that the algorithms and application development will come from three distinct personas:
Developers who are intrigued with quantum computing, developers with a physics background (because there are not many jobs in physics) and those working in high-performance-computing operations. Its a seamless transition from HPC algorithms to quantum, Rutten says.
On the one hand, Google, IBM and others appear to be jostling for position in achieving quantum advantage (the point at which quantum computing can solve a program faster than classical computing) and quantum supremacy (when quantum computing solves a program that no conventional computer can solve). In fact, IBM recently publicly refuted Googles claim of achieving quantum supremacy with its 53-qubit computer, its researchers saying that Google failed to fully estimate the resources of a supercomputer, publishing this in an IBM Research blog last October:
Building quantum systems is a feat of science and engineering, and benchmarking them is a formidable challenge," according to an IBM quantum-computing blog. "Googles experiment is an excellent demonstration of the progress in superconducting-based quantum computing, showing state-of-the-art gate fidelities on a 53-qubit device, but it should not be viewed as proof that quantum computers are supreme over classical computers.
On the other hand, despite the top-tier vendors seemingly jockeying for quantum positions, IDGs Rutten said, its not about competitors going head-to-head. Its hard to compare. No one can tell you [whos ahead] because they are measuring progress in different ways, he says. The notion of quantum being a race is silly.
IDCs West concurs, saying that quantum advances will come from the developer community and technology partnerships. Its not so much a race to the end, because there may not be just one answer.
For its part, IBM has a network of 100 partnerships from commercial (e.g, Goldman Sachs, ExxonMobile, Accenture and others), academic (e.g., MIT, Virginia Tech, Johns Hopkins and dozens of others), startups, government and research sectors.
Even with the likes of Google, IBM and Microsoft pushing quantum computing to go from advantage to supremacy, no one knows where the big innovation will come from, Pizzolato says. The MVP is probably a guy in a lab.
