At Quantum Quest, an all-girls quantum computing camp, 20 teenage female students recently stood on the precipice of a brand new technology: quantum coding.

(Scientists) use quantum computers, program manager Gabbie Meis said. (Quantum computers) actually use quantum mechanics to solve some of the worlds largest problems, like things with lots of data or simulations that our classical computers just dont have enough power to do. Instead of our classical computers, quantum computers are actually an entirely different type of machine that is still being developed today.

This kind of computer requires quantum coding and when programmed could be used to help solve problems like mitigating the impacts of climate change; transportation mapping, such as figuring out how to remap the entire country of Australia with more efficient roadways; or even biomedical research, such as protein folding for vaccine development or drug discovery research.

Back in 2019 Google ran a problem on their quantum computer that they estimated would take the most powerful supercomputer about 10,000 years to solve, Meis said. They said they got their (quantum) computers to solve it in less than two days.

During the camp, students learned the programming language, Qiskit, an open source (free) software development kit. Meis called it a Python-backed library, Python being a programming language. Qiskit allows the students classical computers the kind most of use at home to communicate with quantum computers. Ironically, although the students all had their laptops open, the learning was done on dry erase boards.

Quantum is interdisciplinary so theyre learning the basics in linear algebra, Meis said. Theyre learning computer science and how to code in Python, and theyre learning quantum physics, all wrapped in this single week.

The Coding School, located in Southern California, has a quantum coding initiative called Qubit by Qubit, the most basic unit of information in quantum computing. The initiative seeks to make quantum computing education accessible to students in K-12, because as it stands right now, according to Meis, students dont usually see quantum computing until they are graduate students.

To bring quantum coding to the masses, the school developed the Quantum Quest camp and partners with other organizations to offer it locally. For Tucson, they partnered with the University of Arizonas Office of Societal Impact and the Girl Scouts of Southern Arizona (GSSA).

When this all came about it was the perfect marriage between the Coding School, the U of A and the Girl Scouts in trying to bring accessibility to this more advanced part of STEM, said Colleen McDonald, director of staff supported programs for the GSSA. As Girl Scouts we see ourselves as the connector. We want to make sure that all girls have access to it.

The Coding School has been offering this camp for some time this is its 10th camp but its the first time its been offered in Tucson. Camp topics included everything from foundational concepts that make up the quantum world such as entanglement and qubits, and end with teaching girls how to code real quantum computers.

Its all new science. These students are at the very foundation of quantum coding, according to Meis, and that is part of why it is so important to offer this to young women. One, they are introduced to quantum computing, but two, so they are not alone and do not feel alone in their interest in this field, Meis said.

This is a hard science, right? Meis said. We really want our students to feel that theres a place in this for girls. Were really trying to empower them now while theyre still in high school.

Ive worked with girls for two decades doing STEM with them and one of the biggest things I hear is they think that theyre alone in liking STEM, that they dont realize there are other girls who are also willing to push themselves, Michelle Higgins added. Shes the associate director of the Office of Societal Impact.

The lead instructor for this camp is herself an example to these students. Emily Van Milligen is a doctoral student at the UArizona department of physics. Her field of study is quantum entanglement and routing protocols. She noticed that not one student fell behind; they all listened.

They love it, Van Milligen said. They like the lectures Im giving, which is exciting because that means they enjoy the content. Im not doing anything that special.

One student, 18-year-old Sagan Friskey and future Pima Community College student, spoke enthusiastically about the camp.

I think its super interesting to learn about, especially since were at the very beginning of it becoming a part of something that you can learn about and work with, she said.

Gabriela Malo-Molina, 14, and a student at Catalina Foothills High School, said shes never seen this before but could be interested in looking deeper into it.

I think this is a very special opportunity, and that this field will definitely be more commonly used in the future, she said. And quantum computing in the future will be very helpful for discoveries, especially in the medical field.

String Theory meets music theory at Artown on the Quad – Nevada Today

As temperatures soared into the 90s on the evening of July 12, four musicians with ties to the University came together to emulate how physicists imagined the forces of the universe to come together. The String Theory Quartet, performing as a part of Artown, Renos monthlong celebration of the arts, consists of two alumni who are also siblings, a former alumna-turned-professor and a current instructor.

The quartets cellist is Johnny Lenz. Johnnys father is John Lenz, a renowned former music professor who played cello and horn and played in the Universitys Argenta Trio. As the show started, Johnny fiddled with the tuning of his cello. The quartet had tuned their instruments and rehearsed indoors. He figured the heat might impact the instruments, but the same heat had the quartet retreating to the air conditioned indoors before the concert.

Every single material on Earth has a rate of thermal expansion and contraction, including our strings. As they get longer, the tension decreases in the strings, and they go flat. In the case of my cello, it goes way flat, Lenz said. During his time at the University, he studied the resonance of fine wires. I was pretty good at music, but I was also really good at science and physics.

The former physics student inspired one of the violinists to name the quartet String Theory a reference to the theory of how the forces in the universe impact everything in it. Johnny Lenz was a Westfall Scholar when he graduated in Fall 2006, meaning he had the top GPA of all the physics students that semester. Hes been a musician for 33 years.

The idea behind string theory, and its been a long time since Ive gone to school here, Johnny said, gesturing around, but its unification. Youre trying to unify the different quantum mechanics, classical mechanics, relativity, youre trying to unify all that so that it makes sense. And thats one of the reasons we thought itd be good for a quartet, is were trying to unify and blend the different forces of the musical family and the string instrument family. Ironically, Johnny has always been a string theory skeptic, though his studies focused on experimental physics rather than theoretical.

There arent many jobs in experimental physics in Reno, but Johnny didnt want to leave the area, so he got a job with the Douglas County Sheriffs Office in law enforcement. The sergeant was shot while on duty in December 2020. In honor of Johnnys recovery and return to the stage, the Reno Philharmonic Orchestra offered free virtual access to first responders for a virtual concert in February of 2021 and brought 30 of Johnnys friends, colleagues and family members to the Pioneer Center for an in-person concert.

Johnnys sister, Ruth Lenz, is the concertmaster of the Reno Philharmonic and the Reno Chamber Orchestra and is also a member of the Classical Tahoe Orchestra. Ruth plays the violin and has a doctorate in music performance. She attended the University to get her degree in music. Jessica Escobar, another violinist, taught anthropology and French at the University and is an alum. Escobar came up with the name for the quartet. Dustin Budish, the groups viola player, teaches viola at the University. The group played a diverse mix of music, from the Rolling Stones Paint It, Black to We Dont Talk About Bruno from the Disney movie Encanto to Promentory, the Scottish-inspired main theme from the movie The Last of the Mohicans.

It was really fun, and it was good to be here, Johnny said. Despite the thermal expansion impacting the strings of his cello, the performance received a standing ovation at the end. The event, sponsored by the University and the Edna B. and Bruno Benna Foundation, was the second in a series of free public Artown events called Artown on the Quad.

Another Voice: The physics of unity – Ukiah Daily Journal

I often talk about unity reality. While this is fundamental in the spiritual and metaphysical traditions, I first came to this through physics. High school introduced me to rudimentary atomic theory: atoms were considered as solid spheres, the smallest indivisible portion of a particular element, and molecules were atoms connected in combinations.

A little over a century ago, it was discovered that atoms are mostly empty, because beams of electrons passed through them as if nothing was there. Deeper investigation described atoms having electrons surrounding a very small, relatively massive, nucleus consisting of protons and neutrons.

Hydrogen is the simplest atom, consisting of one electron and one proton, with an effective diameter of 2.510-8 inches, meaning 250 million lined up would measure an inch. That is very small, but the proton in the middle is about 100,000 times smaller, and the electron is 1,000 times smaller than the proton. To give a sense of scale, if the proton was the size of a golf ball, the electron would be the thickness of a piece of newspaper, circling the golf ball at a radius of about 1.4 miles! That 2.8 mile diameter sphere contains only a golf ball and a speck of paper, yet that is what we experience as solid matter.

Quantum mechanics describes electrons in energy shells around the nucleus, neutrons consisting of a proton and an electron, and all the larger particles consisting of combinations of even smaller particles. More significantly, all matter is dense energy, with wave like properties as well as particulate effects. Needless to say, the deeper one looks, the less solid things seem, and the clearer it becomes that all descriptions are approximations.

But physical reality is even stranger than that. About 70 years ago, physicist David Bohm suggested that apparently empty space is actually an almost unimaginably vast ocean of energy: zero-point energy. I first encountered this in Bohms 1980 book, Wholeness and the Implicate Order. While the mathematics are beyond my scope, I have had opportunity to check the implications with several physicists who study this field.

What appears as manifested matter is just a very slight increase in energy, much like a wave on the ocean is a slightly greater amount of water in that particular location, not a separate thing. The perception of different things is a consequence of our limited perspective, not a quality of reality. On the ocean, we perceive only the relative differences in water height, without any awareness of the depths below. Similarly, we experience material form, totally unaware of the underlying energy ocean. As all water waves arise out of the common ocean, all matter arises out of the common energy ocean. Seriously criticized when first proposed, this theory has stood the test of time, continuing to gain credibility as it explains experimental data better than competing theories.

Our sensory systems are designed to detect relative differences, not absolute reality. For example, consider hearing, which depends on an atmospheric density, but only notices the changes in that density, not the absolute value. In addition, we only detect a range of differences, and are unaware of very slow or vary rapid changes, which are noticeable to other species. It is not surprising that we should be unaware of a unity energy field, while noticing only a range of differences.

We are immersed in a complex surface of subtle energy shapes. Just look around at all the colors you see. Every color is a different energy level, ranging from the lowest energy at the red end of the spectrum to the higher energy of blue and ultra violet. The beauty of the world is the variety and subtlety of this energy field. This visible spectrum is a very small part of the measurable energy, and humans see less than other species.

Look around again, considering the idea that all that you see is similar to the wave structure on the surface of the ocean. Every thing has a uniqueness in space and time, yet is a shape of the energy ocean that includes us all. Can you imagine experiencing the connection? Can you feel a taste of the unity reality?

This is our task at this point in human history. The illusion of separation is killing us. We are too numerous and too powerful to be so ignorant much longer.

Worlds top physicists to be in B.C. this summer to bring down sciences greatest mystery – Victoria News

The worlds top physicists will gather in Vancouver this August to launch a Quantum Gravity Institute that could significantly advance our understanding of physics and gravity.

The goal is to discover the theory of quantum gravity, one of sciences greatest mysteries.

Discovering the theory of quantum gravity could lead to the possibility of time travel, new quantum devices, or even massive new energy resources that produce clean energy and help us address climate change, said Philip Stamp, a professor at the University of British Columbia.

The conference will take place between Aug. 15-19, and will welcome two dozen of the worlds top physicists, including Nobel Laureates Jim Peebles, Sir Roger Penrose and Kip Thorne who is well known for developing the original idea for the 2014 film Interstellar.

For roughly 100 years, physics has been based on Einsteins theory of relativity and quantum mechanics.

The theory of relativity has helped us understand the cosmos, leading to space travel and technology like atomic clocks, which govern GPS systems. Quantum mechanics is responsible for the electronics, lasers, computers, cell phones and plastics that support modern transportation, communications, medicine, agriculture and energy systems.

The two theories have provided countless breakthroughs but are seemingly contradictory the theory of quantum gravity is meant to be the bridge between these two theories.

The potential long-term ramifications of this discovery are so incredible that life on earth 100 years from now could look as miraculous to us now as todays technology would have seemed to people living 100 years ago, Stamp said.

The conference will be open to the public on Aug. 17 and provide a once-in-a-lifetime opportunity to learn from the worlds pre-eminent physicists.

Quantum computing and the Australians on the cutting edge – 9News

Fans of Marvel movies know the word 'quantum' too well.

It's the name of the realm the Avengers used to time travel and fantastical as that is, the concept of quantum mechanics is far from fiction.

Scientists have toyed with the idea since the 1920s in an attempt to explain the mysteries of our universe that can not be explained by traditional physics.

The University of Sydney (USYD) and University of New South Wales Sydney (UNSW) are among Google's new partners, which already included Macquarie University (MQ) and the University of Technology (UTS).

Associate Professor Ivan Kassal, from USYD believes advancements in quantum chemistry could develop life saving medicines and help predict the impact of atmospheric matter on our climate.

"Simulating chemistry is likely to be one of the first applications of quantum computers, and my goal is to develop the quantum algorithms that will allow near-term quantum computers to give us insights into chemical processes that are too complicated to simulate on any classical supercomputer," Kassal said.

Those are very physical problems to solve, but the potential of quantum computers could also speed up solving systems, crack cryptography and enable new applications of machine learning.

Australia's Chief Scientist, Dr Cathy Foley said Google's interest in Australia is "testament to the world class research that has been supported by the Australian Research Council for over two decades".

"I am delighted that Google sees Australia as somewhere to do quantum research. A step in building Australia's quantum industry here," said Dr Foley.

Google is building its quantum research team in Sydney, including its newly-appointed quantum computing scientist, Dr Marika Kieferova.

Professor Michael Bremner of UTS said one of this biggest challenges in quantum computing "is understanding which applications quantum computers can deliver performance that goes beyond classical computing."

"In this project, my team at UTS will work with Google on this problem, examining the mathematical structures that drive quantum algorithms to go beyond classical computing," Professor Michael Bremner, UTS

Schrdinger and the conscious universe IAI TV – IAI

Most assume that matter is fundamental, and that consciousness arises out of the complexity of matter. But Nobel Prize winning quantum physicist Erwin Schrdinger does not share that assumption. For him, the universe contains a single mind, writes Robert Prentner and Donald D. Hoffman.

In February 1943, Erwin Schrdinger, quantum physicist and Nobel laureate (sharing his prize with Paul Dirac and Werner Heisenberg), gave a series of lectures at Trinity College Dublin, which later turned into his book What is life? [1]. This work has been highly influential for a generation of molecular biologists such as Francis Crick, one of the discoverers of DNA. Less known perhaps is the fact that during his whole life Schrdinger was an ardent reader of philosophy from the East and West. From the 1950s on, when Schrdinger ceased to actively work on the physics of his time, he focused more on wider philosophical and ethical issues related to science. Back then, his conferences always ended with what he jokingly called the second Schrdinger equation: Atman = Brahman, the Indian doctrine of identity.

The present article investigates some of these ideas and gives them a reading in terms of a recent theory of consciousness. We believe that, just as Schrdingers ideas on the physical basis of life have inspired groundbreaking work in molecular biology, his ideas on mind and reality might inspire groundbreaking work in understanding the nature of consciousness and its relation to physics.

___

Early on, Schrdinger expressed the conviction that metaphysics does not come after physics, but inevitably precedes it. Metaphysics is not a deductive affair but a speculative one.

___

In 1925, just a few months before Schrdinger discovered the most basic equation of quantum mechanics, he wrote down the first sketches of the ideas that he would later develop more thoroughly in Mind and Matter. Already then, his thoughts on technical matters were inspired by what he took to be greater metaphysical (religious) questions. Early on, Schrdinger expressed the conviction that metaphysics does not come after physics, but inevitably precedes it. Metaphysics is not a deductive affair but a speculative one.

The many meanings of Schrdinger's catRead more One such speculative assumption (which can neither be proven nor disproven) is the one that there exists an external (mind-independent) world. Another one is the assumption that there exist separate minds. For both claims, according to Schrdinger, we cannot get any empirical evidence: how could we step out of our own experience to check them? But both create insurmountable problems. The first creates the problem of how to think about the relation between these two types of realities (mind-matter). Why does it appear (according to our best science) that we live in a purely physical world devoid of qualities? The second creates the problem of how to think about the relation between different minds (mind-mind). Why and how are we different from each other? Schrdinger believed that there is an elegant way to dissolve both of these problems by starting with an alternative metaphysical assumption. He did not endorse traditional Western views that go under the names of reductive materialism and subjective idealism, but he found inspiration in non-Western, particularly Indian philosophies.

___

We are all but aspects of one single mind that forms the essence of reality.

___

His second Schrdinger equation refers to an old staple of Indian philosophy according to which the self (Atman) is identical to the ultimate reality of the universe (Brahman), which forms a central part of the teachings of the Advaita Vednta. Schrdinger was quick to add that this self must not be conflated with the individual self but rather refers to a cosmic, universal entity of which individual selves are mere aspects.

A metaphor that Schrdinger liked to invoke to illustrate this idea is the one of a crystal that creates a multitude of colors (individual selves) by refracting light (standing for the cosmic self that is equal to the essence of the universe). We are all but aspects of one single mind that forms the essence of reality. He also referred to this as the doctrine of identity. Accordingly, a non-dual form of consciousness, which must not be conflated with any of its single aspects, grounds the refutation of the (merely apparent) distinction into separate selves that inhabit a single world.

___

Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world.

___

Schrdinger drew remarkable consequences from this. For example, he believed that any man is the same as any other man that lived before him. In his early essay Seek for the Road, he writes about looking into the mountains before him. Thousands of years ago, other men similarly enjoyed this view. But why should one assume that oneself is distinct from these previous men? Is there any scientific fact that could distinguish your experience from another mans? What makes you you and not someone else? Similarly as John Wheeler once assumed that there is really only one electron in the universe, Schrdinger assumed that there really is only one mind. Schrdinger thought this is supported by the empirical fact that consciousness is never experienced in the plural, only in the singular. Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world. [7]

In the contemporary scientific study of consciousness, many scholars try to circumvent the question of how and why matter gives rise to conscious experience by asking why there seems to be a hard problem in the first place (when there is in fact none): consciousness is an illusionary story that some physical systems equipped with brains tell themselves. While Schrdinger was far from accepting an illusionary stance about the reality of consciousness, in a very similar vein he asks why it seems as if there were a multiplicity of minds, where there is just one mind (the Atman=Brahman): the existence of many separate minds is an illusionary story that confused individuals would tell themselves. Thinking otherwise leads to the false belief that we are in some sense fundamentally isolated, rather than realizing that we are always connected with other beings (and ultimately also with what we now call non-living matter). Unlike in the hard problem case, there is no empirical evidence to suggest our initial belief is real.

An important characteristic of the way Schrdinger approached metaphysical and philosophical teachings was his prudence to uphold a rational and scientific methodology. The doctrine of identity cannot be adopted uncritically. We need to incorporate the doctrine into our best science, not throw our best science overboard. In other words, we should adopt a new metaphysics but keep with the scientific method. Our scientific theories need a bit of blood transfusion from Eastern thought [but] transfusions always need great precaution to prevent clotting. We do not wish to lose the logical precision that our scientific thought has reached, and that is unparalleled anywhere at any epoch. [8]

What Schrdinger sought, what he would have appreciated the most, is a scientific approach to studying consciousness with mathematical precision. An important constraint following from the doctrine of identity for any such theory of consciousness would be that it, in its very basic structure, acknowledges that individual conscious beings are (i) aspects of a higher, unifying agent (rather than being disconnected individuals), and (ii) that the entire collection of such beings constitutes the ultimate nature of reality (rather than being just one among many things such as electrons, rocks, or brains.)

Schrdinger desired a radically monist-theory that acknowledges the reality of consciousness. Given the current theoretical landscape in the study of consciousness, the theory of conscious agents [9] seems to fit best with these requirements. It aims for a precise, crisp formulation of what consciousness does, and it proposes that any combination of two or more conscious agents is itself another agent. It also seems to be compatible with the idea that the entire collection of agents constitutes the nature of reality, though this requires the theory to come up with a model of how the physical world can arise (and be nothing apart) from this collection.

___

According to the theory of conscious agents, the idea of fundamentally separated selves is a useful fiction that arises only if we conflate what we see on the interface with the true reality of non-dual consciousness.

___

How could this be so? Schrdinger relied on a couple of arguments that have been raised previously in philosophy (e.g. by Kant) but his position boils down to this: what we call the physical world is the result of a process that Schrdinger called objectivation, i.e. the transformation of the one self-world (Atman=Brahman) into something that can be readily conceptualized and studied objectively, hence something that is fully void of subjective qualities. In the theory of conscious agents this amounts to the creation of interfaces. Such interfaces simplify what is going on in order to allow you to act efficiently. Good interfaces hide complexity. They do not let you see reality as it is but only as it is useful to you. What you call the physical world is merely a highly-simplified representation of non-dual consciousness.

This physical world also appears to harbor a multitude of subjects directed at it. It is the very same process of objectivation, which led to the false impression of an autonomous physical world, that also leads to the fallacy of assuming different forms of consciousness inhabiting different bodies. The quick fix of adding mental properties to a non-mental world would not be able to really solve the problems mentioned earlier. Where to put them? Do we need to label them with a tag saying individual x? But then, why are you you and not someone else? How to combine one set of subjects into a higher one? But those problems can be circumvented by never giving in to the metaphysical assumption of the existence of one physical world that is opposed to many separated selves in the first place. According to the theory of conscious agents, the idea of fundamentally separated selves is a useful fiction that arises only if we conflate what we see on the interface with the true reality of non-dual consciousness.

The theory of conscious agents proposes an interesting answer to Schrdingers questions. Why does it appear that we are living in a physical world without qualities? Why and how are we different from each other? Because the dynamics of conscious agents results in the creation of interfaces that hide the true character of reality. We are the same, yet we can appear as different. From one perspective all agents combine into a single one which equals a (single) world. From a different perspective, this single agent is equal to a network of distinct agents that all inhabit their own worlds. Which perspective we choose, depends on what we want to explain.

Rosanne Cash Reflects on Her Life and Legacy – NPR

MANOUSH ZOMORODI, HOST:

It's the TED Radio Hour from NPR. I'm a Manoush Zomorodi.

And if you've ever heard a song and instantly been transported back in time, you know the power of music to punctuate an event in your life or distill a moment in history. Musician Rosanne Cash calls this the rhythm and rhyme of memory. And she says it's the force behind her songwriting.

ROSANNE CASH: There's a mystery and a magic at the center of this process that's really undefinable and unexplainable. And when you touch that, you're touching something of the divine. It's this creative source.

ZOMORODI: That creative source has led her to record 15 albums over the past four decades and win four Grammy Awards. It also, she says, helped her accept the scrutiny that came with being the legendary Johnny Cash's daughter and, more recently, confront America's painful past, including her family's own role in that history.

R CASH: I often don't know what I feel or think. And I don't know how to process things. And I don't know what I want until I write about it.

ZOMORODI: On this episode, we explore the links between memory and music with singer, songwriter and musician Rosanne Cash, who is incredibly cool and funny and punctual.

Wait a minute, it's exactly 9 a.m. and we're both recording and ready to go.

R CASH: (Laughter).

ZOMORODI: How is that even possible?

R CASH: It's unheard of.

(SOUNDBITE OF SONG, "A FEATHER'S NOT A BIRD")

R CASH: (Singing) A stone is not a mountain, but a river runs through me.

ZOMORODI: And off we go.

Rosanne Cash, hello, and thank you so much for being here.

R CASH: Hi, Manoush. I'm thrilled to talk to you.

ZOMORODI: So, Rosanne, I have to imagine that as the daughter of Johnny Cash, there was probably a good amount of music in your life as a child. Was it something that was just everywhere? I mean, I know that your dad had his first single put out just a couple months after you were born.

R CASH: About a month, actually.

(SOUNDBITE OF SONG, "CRY, CRY, CRY")

JOHNNY CASH: (Singing) I wasted my time when I would try, try, try 'cause when the lights have lost their glow, you'll cry, cry, cry.

R CASH: Yeah. It was in the house all the time - and not just what my father was playing - you know, Jimmie Rodgers and Woody Guthrie and, you know, Hank Williams and all of the older country stars and Sister Rosetta Tharpe and the gospel and blues. All of that was around.

(SOUNDBITE OF SONG, "UP ABOVE MY HEAD")

SISTER ROSETTA THARPE: (Singing) Up above my head. Up above my head. I hear music in the air.

R CASH: But then when my dad was on the road, what my mother played was also incredibly influential. She loved Patsy Cline.

(SOUNDBITE OF SONG, "STRANGE")

PATSY CLINE: (Singing) Well I guess that I was just your puppet you held on a string.

R CASH: And then when I was old enough to discover the songs on the radio for myself, then it was the Beatles.

(SOUNDBITE OF SONG, "I SAW HER STANDING THERE")

THE BEATLES: (Singing) Well, she was just 17.

R CASH: I learned to love the Beatles and Patsy Cline and blues and Southern gospel and Marty Robbins and, you know, Crosby, Stills, Nash & Young. It was all swirling around.

ZOMORODI: In the talk you gave in 2021, which is called "The Rhythm And Rhyme Of Memory, Solitude And Community," you say that in your family there was a song for every loss, every celebration, every unspoken need, every longing. And I guess I would think, wow, that is a family that is great at communicating with each other. But that was not necessarily the case, right?

R CASH: No. Well, what you describe is the - if that was actually carried out, if that was actually something that was happening, the idea that we could sit down and go, this is how I'm feeling, and here's the song for it - no. What happened is that I found those songs for myself. They helped explain me to my selves, you know, that indefinable longing or sadness or melancholy or hope or loss or thrill. There were songs for every most nuanced expression of all of those emotions. There are songs for each one. And I was able to find them, you know?

There's something in my DNA that was attuned to that language. But the - my house was much more chaotic. I think that the - music is how I made sense of a lot of things, and it was my particular kind of special cave that I went into. You know, my father was a drug addict in my early years. My mother was not equipped to handle either a partner who was a drug addict or fame. And those are the two things that kind of permeated our household - and then my mother's anger and fear and grief about all of those things. So there was not a lot of room for other emotion.

And I think me and my sisters were - we didn't have anything explained to us. You know, they didn't talk to kids back then. There was no way they were going to sit down and say, look, your father's a drug addict, and here's what's happening. No. So the confusion and fear, you know? - and children think, oh, that's - this has to be my fault. It was complicated.

ZOMORODI: What were some of the ways that you coped with having a dad who was so famous?

R CASH: The thing is, is that I my family was so abnormal that I looked for, what did normal families do? I loved the "Little House On The Prairie" series because, you know, the washing was on Monday, and the baking was on Tuesday. And you did this and you didn't wear this, and you didn't speak like this. And I thought, OK, that's normal. And I wanted to create my own sense of normalcy.

ZOMORODI: So if you didn't live a normal childhood and you were looking for normalcy, what are some of your first memories, or what did you think you would grow up to become?

R CASH: Oh, I knew I would be a writer. I had a dream when I was 13 years old, and it was of my mother and my grandmother. And they were sitting at a card table. And they were vacant, just vacant behind the eyes and rote in their actions. And they kept putting cards slowly on the table to each other. And I woke up in a sweat at 13. And I said to myself, I will never be a card player. And I wrote my dad a letter - my dad was on the road - about my - those impulses. I didn't want to live in that kind of deadening routine. I wanted to do something that touched the divine. I didn't use those words at that time. But he wrote me back, and he said, I see that you see as I see.

ZOMORODI: Wow.

R CASH: And I held on to that. And I realized that there was a template for me to be who I was in the world, and it wasn't to copy, but it was to explore and find myself. And in some ways, my dad and I had a simpler relationship than I had with my mother. She saw that I was - there was some kind of DNA thread that was similar to my dad's, that I was an artist. And I think she saw that from a young age, and it terrified her.

ZOMORODI: So you started writing pretty early on.

R CASH: Yeah. Well, I did write poetry starting from about the age of 8 or 9. Rhyme and language were already - even from the time I was 3, my mother said, you asked what every word said and what it meant. So I was writing poetry all through my teens. And then at some point - this babysitter I had wrote to me, you know, like 10, 15 years ago and said, I babysat you. And I remember you said, how do you put poetry to music? And I thought to myself, why was I asking her?

(LAUGHTER)

R CASH: I had a better authority in my own house. But yeah, that's what happened, is that when I learned to play guitar, I started writing songs. And that was about age 18.

ZOMORODI: You tell a story in your TED Talk about some writing you did when you were younger - this phrase that you came up with that ended up revisiting you later in life and really influencing you.

R CASH: Yeah. I was in my mid-30s, and I was working on a song. And my mom at the same time across the country was going through my school papers and drawings and, you know, things from childhood of mine that she'd saved. And she sent me this whole box. And I was leafing through the box, and I came across this paper I had done in seventh grade on metaphors and similes.

And I looked at this paper, and I - it suddenly just washed over me. The thrill I had felt in doing that paper was the first time that I had ever been excited about anything that they had asked me to do in Catholic school. And there was this metaphor I had written. A lonely road is a bodyguard. This is a beautiful metaphor that I wrote at 12 years old. And it really moved me and struck me. And I just took that line and put it right in the song I was writing. The song's called "Sleeping In Paris."

ZOMORODI: Here's Rosanne Cash performing on the TED stage.

(SOUNDBITE OF TED TALK)

R CASH: (Singing) I'll send the angels to watch over you tonight, and you send them right back to me. A lonely road is a bodyguard if we really want it to be.

A lonely road is a bodyguard. What did it mean? I had even pasted a picture of this empty road next to the line. So my 12-year-old waved at me across the decades saying that who I was was who I would become. As painful as that was then and as it still can be painful now, I knew what she was telling me - that solitude can protect the seeds of creativity and that loneliness contains a priceless gift. If we can tolerate the initial discomfort and avoid the seduction of despair, we're all just radios hoping to pick up each other's signals. And some of those signals have a backbeat and a melody, and they're universal. And music can unlock a frozen memory that melts into the seeds of our creativity. And the reverse is also true. A memory can unlock a song that's waiting to be written.

ZOMORODI: When we come back, more with Rosanne Cash, including a recent revelation about her mother that adds a twist to her family's history. I'm Manoush Zomorodi, and you're listening to the TED Radio Hour from NPR. Stay with us.

(SOUNDBITE OF SONG, "DANCE WITH THE TIGER")

R CASH: (Singing) Of just how alone are all who live here.

ZOMORODI: It's the TED Radio Hour from NPR. I'm Manoush Zomorodi, and with me for the hour is Rosanne Cash.

Hi, Rosanne.

R CASH: Hi, Manoush.

ZOMORODI: So we were talking about your dad, Johnny Cash. In the '60s, he moved your family from Tennessee to California. But as you said, it was kind of a tough childhood. As your father's success exploded, your parents' relationship really suffered. And I think most people know more about your dad's second wife, June Carter. But tell us about your mom, his first wife, Vivian, because she was a quiet but intense character.

R CASH: She wasn't very quiet at home.

(LAUGHTER)

R CASH: She was very intense. She's Sicilian, you know? She was very private and was not equipped to deal with my dad's sudden fame - explosive fame - and then his subsequent drug addiction. You know, in the '60s, it was like - he would have to drive 200 miles and do three shows a night, you know, on these tours. And at some point, someone gave a pill to him and said, take this. It'll keep you awake. Take this, and it'll help you sleep afterwards. And then that was it.

So my mom was not prepared for that. And then, you know, her - the template she had later on - when I went into, you know, became a songwriter and she realized that this was going to be my life path, she - her template for that was, oh, you get on drugs. You get divorced. Your family falls apart. You're never home, you know? And she was terrified that that's - was going to be my life.

ZOMORODI: Did you reassure her and say, no, I've learned from what not to do?

R CASH: No. I was not in the business of reassuring my mom anything at the age of 18.

(LAUGHTER)

R CASH: I just wanted to get away.

ZOMORODI: Just to step back for a second, in the beginning of your parents' relationship, they were madly in love.

R CASH: Absolutely. My dad was in the Air Force for three years. And my sisters and I have 1,000 letters they wrote to each other.

ZOMORODI: Wow.

R CASH: Yeah.

ZOMORODI: That's crazy - a thousand. And is he saying, like, I'm going to be a big musical superstar?

R CASH: No, he was - it was mostly besotted teenage love. You know...

(SOUNDBITE OF ARCHIVED RECORDING)

J CASH: I do, Vivian. I love you very much. I love you more than anything in the world. We'll be together soon.

R CASH: My darling, my darling, my darling, and then, you know, he would throw in, I bought this record. I bought a cheap guitar. I have a little band with two of the other, you know, Air Force guys. And so there were these sprinklings of what was being seeded in him at that time.

ZOMORODI: And so there was this period where your parents were really happy.

R CASH: Oh, yeah - I mean, until I was about 6, I think. You know, it was great. They were in love. They were building a life together. Like you said, we moved to California when I was 3 from Memphis. And then things started falling apart.

ZOMORODI: I had read the story - I knew in the history books that in 1965 your father was arrested in Texas for drug possession. But I didn't know the story that your mom went down to get him out of jail and that there's a famous photo that was taken as they left the courthouse. And the public had, I mean, outrageous reaction to this photo. Can you explain what happened?

R CASH: Well, it was a, you know, a photo in the newspaper - not very pixelated, as it was back then. And it was dark. And my mother's features are Sicilian. And it appeared that she was African American. And there was this outcry that my father had married a Black woman. And the Ku Klux Klan started this campaign against my father to ban his records. And, you know, they excoriated him in the press. And it was this kind of - it got very intense and scary. And I didn't know what this was all about. But it was very frightening.

And he had to - he wrote this letter, you know, saying that my mother was Italian. And, you know, this went on for a while. And my mother was, like I said, so private. And she was extremely embarrassed by this attention - you know, something about her appearance or about her history or her race. And that was incredibly hard for her to process. It was too much attention and in the wrong way.

ZOMORODI: And there is actually another layer to this story, because your mother always believed that she came from an Italian American family, but you recently learned that there actually is some African heritage, too.

R CASH: It's so fascinating. I did "Finding Your Roots" a few years ago. And my mother's paternal side was, indeed, 100% Sicilian. They - you know, her grandparents immigrated from Sicily in the late 1900s and opened a store in San Antonio. All of this is well documented. And - but it turns out on her maternal side, whose history goes back deep in America, that in the 1840s there was a freed slave married to - actually, I don't know if they could get married, but they were living as man and wife in Alabama in the 1840s. They had nine children together. And one of those children is my grandmother's - my maternal grandmother's - direct ancestor.

ZOMORODI: Yeah. It's an amazing coda to this chapter in your family's history. Was it on your mind when you wrote the song "The Killing Fields"? You sing about your family's Southern roots and the history there of lynchings and racism in the South. It is haunting.

R CASH: Yeah. So writing "The Killing Fields" was a slow awakening. And I do not claim to be awakened about race and about the suffering of African Americans and about the history of slavery. But I am - I want to be awakened about it.

(SOUNDBITE OF SONG, "THE KILLING FIELDS")

R CASH: (Singing) There was cotton on the killing fields. It blows down through the years. It sticks to me just like a burn, fills my eyes and ears. And all that came before me...

And I had already been thinking about race. My grandfather - Cash - had a deep thread of racism running through him - you know, Arkansas farmer. And he was not well educated. And I'm not making excuses for him. It was a - it's a very painful thing to acknowledge about him. But I had been involved with the restoration of my dad's boyhood home in Arkansas for the past 12 years, 14 years. And going to Arkansas a lot, I became more aware of the really dark, dark history of racism and violence in Arkansas.

At around the same time, I was doing a show at Dockery Farms in Mississippi, which is really one of the birthplaces of the blues. It was a cotton farm where some of the great blues artists - Howlin' Wolf and Charley Patton - had picked cotton in the day and played guitar and music and juke joints at night. So doing this show, there was an after-party, all white people at the after-party and this nearly 90-year-old Black man playing blues harp with a guitarist - a white guitarist - at the after-party while the white people were milling around. And I kept looking at him all night.

And I went over to him after the party to say thank you so much, you know? That was so beautiful. Really appreciate you coming and playing. And he said, oh, I just want to tell you that when I was out behind the plow in the fields, that we had a radio sitting on the porch. And whenever your daddy came on the radio in the '50s, I would run over to listen to him. And I started weeping. I was thinking about my racist grandfather across the river in Arkansas behind the same kind of plow. And I realized that everything I do musically, creatively - that in some ways there's a thread that goes back to that Black man behind the plow in Mississippi musically and that white man behind the plow in Arkansas. And I started thinking about the threads you have to break in your life - the ones you bind, the ones you break.

(SOUNDBITE OF MUSIC)

ZOMORODI: OK. So that reminds me of another story you tell in your TED Talk about your grandmother, Carrie Cash, and what it was like to be a woman in the South - the American South - a century or so ago.

R CASH: Yeah. So she had seven children - one who died when he was 14. But she gave birth at home with the assistance of a doctor who came by in a horse-and-buggy to check on her. One of her labors - she was in labor for three days - he came by on a horse-and-buggy to check on her every day, once a day and pulled two aspirin from his pocket to give her. It was the same pocket in which he kept his fishing worms.

ZOMORODI: Wow.

R CASH: I know (laughter).

ZOMORODI: Here's Rosanne Cash again on the TED stage.

(SOUNDBITE OF TED TALK)

R CASH: I read once that every time an old woman dies, a library disappears. And before her library disappeared, I tuned in to my grandmother's signals and gleaned her tenacity, which I borrowed, and her long suffering and her life of constant work with seven children - six of whom made it to adulthood - in a house without electricity in the sweltering cotton fields. And I wrote these words about her.

(SOUNDBITE OF SONG, "THE SUNKEN LANDS")

R CASH: (Singing) Five cans of paint in the empty fields, and the dust reveals. And the children cry. The work never ends. There's not a single friend. Who will hold her hand in the sunken lands? And the mud and tears melt the cotton bolls. It's a heavy toll - oh, oh. His words are cruel, and they sting like fire, like the devil's choir - oh, oh. But who will hold her hand in the sunken lands? The river rises, and she sails away. But she could never stay - oh, oh. Now her work is done in the sunken lands. There's five empty cans.

(APPLAUSE)

Physicists Create Mind-Bending New Phase of Matter That Acts Like It Has Two Time Dimensions – SciTechDaily

Physicists have created a remarkable, never-before-seen phase of matter in a quantum computer.

Physicists demonstrated a way of storing quantum information that is less prone to errors by subjecting a quantum computers qubits to quasi-rhythmic laser pulses based on the Fibonacci sequence.

Physicists have created a remarkable, never-before-seen phase of matter by shining a laser pulse sequence inspired by the Fibonacci sequence at atoms inside a quantum computer. Despite there still being only one singular flow of time, the phase has the benefits of two time dimensions, the physicists reported on July 20 in the journal Nature.

This mind-bending property offers a highly desirable benefit: Information stored in the phase is far more protected against errors than with alternative setups currently used in quantum computers. As a result, the information can exist for far longer without getting garbled, an important milestone for making quantum computing viable, according to study lead author Philipp Dumitrescu.

The approachs innovative use of an extra time dimension is a completely different way of thinking about phases of matter, says Dumitrescu, who worked on the project as a research fellow at the Flatiron Institutes Center for Computational Quantum Physics in New York City. Ive been working on these theory ideas for over five years, and seeing them come actually to be realized in experiments is exciting.

In this quantum computer, physicists created a never-before-seen phase of matter that acts as if time has two dimensions. The phase could help protect quantum information from destruction for far longer than current methods. Credit: Quantinuum

Together with Andrew Potter of the University of British Columbia in Vancouver, Romain Vasseur of the University of Massachusetts, Amherst, and Ajesh Kumar of the University of Texas in Austin, Dumitrescu spearheaded the theoretical component of the research. A team headed by Brian Neyenhuis conducted the experiments on a quantum computer at Quantinuum in Broomfield, Colorado.

Ten atomic ions of the element ytterbium serve as the workhorses of the teams quantum computer. Each ion is individually held and controlled by electric fields produced by an ion trap and can be manipulated or measured using laser pulses.

Each of those atomic ions function as what physicists dub a quantum bit, or qubit. As opposed to conventional computers that quantify information in bits (each representing a 0 or a 1), the qubits used by quantum computers leverage the strangeness of quantum mechanics to store even more information. Just as Schrdingers cat is both dead and alive in its box, a qubit can be a 0, a 1, or a mashup or superposition of both at the same time. That additional information density and the way qubits interact with one another promise to allow quantum computers to solve computational problems far beyond the reach of traditional computers.

The Penrose tiling pattern is a type of quasicrystal, which means that it has an ordered yet never-repeating structure. The pattern, composed of two shapes, is a 2D projection of a 5D square lattice.

However, theres a big problem: Just as peeking in Schrdingers box seals the cats fate, so does interacting with a qubit. And that interaction doesnt even have to be deliberate. Even if you keep all the atoms under tight control, they can lose their quantumness by talking to their environment, heating up or interacting with things in ways you didnt plan, Dumitrescu says. In practice, experimental devices have many sources of error that can degrade coherence after just a few laser pulses.

Therefore, the challenge is to make qubits more robust. To do that, physicists can use symmetries, which are essentially properties that hold up to change. (For example, a snowflake has rotational symmetry because it looks the same when rotated by 60 degrees.) One method is adding time symmetry by blasting the atoms with rhythmic laser pulses. This approach helps, but Dumitrescu and his collaborators wondered if they could go further. So instead of just one time symmetry, they aimed to add two by using ordered but non-repeating laser pulses.

The best way to understand their approach is by considering something else ordered yet non-repeating: quasicrystals. A typical crystal has a regular, repeating structure, like the hexagons in a honeycomb. A quasicrystal still has order, but its patterns never repeat. (Penrose tiling is one example of this.) Even more mind-boggling is that quasicrystals are crystals from higher dimensions projected, or squished down, into lower dimensions. Those higher dimensions can even be beyond physical spaces three dimensions: A 2D Penrose tiling, for instance, is a projected slice of a 5D lattice.

For the qubits, Dumitrescu, Vasseur, and Potter proposed in 2018 the creation of a quasicrystal in time rather than space. Whereas a periodic laser pulse would alternate (A, B, A, B, A, B, etc.), the researchers created a quasi-periodic laser-pulse regimen based on the Fibonacci sequence. In such a sequence, each part of the sequence is the sum of the two previous parts (A, AB, ABA, ABAAB, ABAABABA, etc.). This arrangement, just like a quasicrystal, is ordered without repeating. And, akin to a quasicrystal, its a 2D pattern squashed into a single dimension. That dimensional flattening theoretically results in two time symmetries instead of just one: The system essentially gets a bonus symmetry from a nonexistent extra time dimension.

Actual quantum computers are incredibly complex experimental systems, though, so whether the benefits promised by the theory would endure in real-world qubits remained unproven.

Using Quantinuums quantum computer, the experientialists put the theory to the test. They pulsed laser light at the computers qubits both periodically and using the sequence based on the Fibonacci numbers. The focus was on the qubits at either end of the 10-atom lineup; thats where the researchers expected to see the new phase of matter experiencing two time symmetries at once. In the periodic test, the edge qubits stayed quantum for around 1.5 seconds already an impressive length given that the qubits were interacting strongly with one another. With the quasi-periodic pattern, the qubits stayed quantum for the entire length of the experiment, about 5.5 seconds. Thats because the extra time symmetry provided more protection, Dumitrescu says.

With this quasi-periodic sequence, theres a complicated evolution that cancels out all the errors that live on the edge, he says. Because of that, the edge stays quantum-mechanically coherent much, much longer than youd expect.

Though the findings demonstrate that the new phase of matter can act as long-term quantum information storage, the researchers still need to functionally integrate the phase with the computational side of quantum computing. We have this direct, tantalizing application, but we need to find a way to hook it into the calculations, Dumitrescu says. Thats an open problem were working on.

Physics Major Works on a New Theory of Quantum Subsystems – Dartmouth News

When studying a complex system, scientists identify smaller pieces called subsystems that they can make sense of. By studying subsystems and the correlations between them, they reconstruct an understanding of the whole.

This approach has been used with great success to explain phenomena and develop applications in computing, cryptography and sensing based on quantum mechanicsthe physics of matter and energy at the scale of the atom or smaller. But this approach is limited to systems that operate in a world where time is absolute.

This description of subsystems falls short when describing scenarios that involve Einsteins theory of general relativity, where time is relative to an observers motion and tightly interwoven with space into a four-dimensional spacetime.

Now, a theoretical study co-authored byAlexander Smith, assistant professor of physics at Saint Anselm College and adjunct assistant professor at Dartmouth, and Shadi Ali Ahmad 22, proposes a new way to identify subsystems and correlations compatible with general relativity.

Theoretical physicists have long been striving to combine quantum mechanics and general relativity into a unified theory of quantum gravity. It is hoped that this work may be applied in developing a quantum description of spacetime, says Smith.

The results, published in April inPhysical Review Letters, build on previous work on a generalized notion of subsystems by the James Frank Family Professor of Physics Lorenza Violaand her collaborators. Instead of having composite building parts that are glued together into a larger system, subsystems should be thought of as directly arising from the observable properties one can measure, says Viola.

Quantum mechanics allows for correlations that are not consistent with our classical understanding of the world, says Smith, Viola and her collaborators gave us a new way to think about these unintuitive quantum correlations.

Smith, Ali Ahmad and their collaborators apply this idea to build a framework for identifying subsystems, which is consistent with relativity, and find that the notion of the subsystem is no longer rigid.

The way we partition a system is also relative. It depends on who is looking at it, says Smith. While their method currently applies to simple systems of several particles, the authors are working to generalize the framework to quantum field theory, which constitutes our most fundamental description of nature.

Several theoretical concepts that are driving the emerging understanding of quantum gravity have their origin in quantum information theorya relatively new field that studies how information in a quantum system can be analyzed and manipulated. Quantum information science has given us this whole new way to think about quantum mechanics itself, says Smith.

Working with Smith and other researchers, Ali Ahmad, a physics and mathematics major from Beirut, has used quantum information theory to study a number of different theoretical problems. Inprevious work, they were the first to examine how gravitational wavesripples in spacetime produced when massive astronomical objects (e.g. black holes) speed up to extreme levelsaffect entanglement between systems.Another projecttackled the question of how workthe measure of how much energy is transferred when a force acts on an objectcan be defined operationally at the quantum scale.

Smith says Ali Ahmad is one of the most driven to learn, hardworking and productive students he has encountered. Seeing Shadi develop his ability in theoretical physics over the past four years has been very rewarding, he says.

Ali Ahmad won the 2022 Gazzaniga Family Science Award, which recognizes scientific accomplishment of a graduating senior in the sciences. He is also the recipient of the Physics and Astronomy Chairs Prize.

Quantum information theory is a toolbox that I like to borrow from and use broadly, says Ali Ahmad. The promise of access to undergraduate research opportunities and funding was what drew him to Dartmouth, he says. Now a research fellow at Dartmouth, Ali Ahmad is wrapping up ongoing projects as he prepares to apply to graduate programs.

With classes as a springboard, he sought out research mentors in the physics and mathematics departments, collaborating with them on a wide range of research topics. Talking about science with people shapes the way you think, says Ali Ahmad, who already has three publications under his belt. I think it really sharpens your interests.
