‘Butterfly effect’ is wrong and reality can ‘heal itself’, quantum scientists find in time travel experiment – The Independent

Scientists have disproved the butterfly effect at the quantum level, refuting the idea that changes made in the past would have grave ramifications upon returning to the present.

In the simulation, a piece of information is simulated to be sent backwards in time. That information is then damaged. However, when the information returns to the present it is largely unaltered and, counter-intuitively, with travels further into the past the final piece of information returns with less damage.

Such an effect only works in quantum mechanics, in simulations conducted via quantum computers, because time travel is not yet possible.

Sharing the full story, not just the headlines

On a quantum computer, there is no problem simulating opposite-in-time evolution, or simulating running a process backwards into the past, said Nikolai Sinitsyn, a theoretical physicist at Los Alamos National Laboratory, in a statement.

We can actually see what happens with a complex quantum world if we travel back in time, add small damage, and return. We found that our world survives, which means there's no butterfly effect in quantum mechanics.

To test the butterfly effect, the researchers used an IBM-Q quantum processor with quantum gates, which simulate forwards and backwards cause and effect.

Standard computers and processors use bits in their chips, which exist in two positions - either on or off which is the makeup of binary.

Quantum computers use qubits rather than bits, which can be both be on and off simultaneously, as well as somewhere in between.

In the simulation, a person sends a qubit back in time. An intruder in the past measures the qubit, which disturbs it and changes its quantum correlations.

This is because even slight contact between an atom exhibiting quantum behaviour and another atom will immediately move the atom out of its quantum state.

The simulation is then run forward, to bring the qubit to the present day. It was found that, rather than the information being unrecoverable due to extrapolation of the small inciting incident the act of stepping on a butterfly in the common metaphor it was protected from minor tampering.

We found that the notion of chaos in classical physics and in quantum mechanics must be understood differently, Sinitsyn said.

The discovery could be used to hide information converting it from its initial state into one of quantum entanglement and could also be used to test quantum devices.

Since the lack of butterfly effect exists in quantum mechanics, if the simulation is run and the result is different it would prove that the quantum processor is not working effectively.

Research: the butterfly effect does not exist in the quantum model – FREE NEWS

Scientists at Los Alamos National Laboratory used a quantum computer and simulated a time travel model. They found that the butterfly effect did not exist in their experiment.

The researchers used a quantum computer to simulate time travel and showed that there is no butterfly effect in the quantum model. They used quantum bits and sent them to a simulated past. In this case, one of the bits was damaged during sending, but it did not damage other bits that were sent along with them.

The simulation involved two hypothetical humans, Alice and Bob, each with a qubit a quantum bit of information. During the experiment, Alice sent her qubit to the past, but at some point, Bob intervened in it and changed the information in it. However, despite the changes, Alice was able to recover the information when the qubit returned.

This way we can really see what happens to the complex quantum world if we travel through time, add a little damage and come back. We found that this does not harm the present, which means there is no butterfly effect in quantum mechanics.

Nikolay Sinitsyn, co-author of the work

The researchers repeated the experiment and found that simulating the return of a qubit to the past and inflicting damage on it has little or no effect on the information it carries. This effect can be applied in areas where quantum devices must carry secret information. Data can be hidden by transforming the original state into a confusing one.

We found that even if an attacker manipulates in a highly entangled state, we can still easily recover useful information since this damage does not increase with decoding, the scientists noted.

Solving problems by working together: Could quantum computing hold the key to Covid-19? – ITProPortal

Given the enormous potential for quantum computing to change the way we forecast, model and understand the world, many are beginning to question whether it could have helped to better prepare us all for a global pandemic such as the Covid-19 crisis. Governments, organisations and the public are continuing the quest for answers about when this crisis will end and how we can find a way out of the current state of lockdown, and we are all continuing to learn through incremental and experimental steps. It certainly seems plausible that the high compute simulation capabilities of our most revolutionary technology could hold some of the answers and enable us to respond in a more coherent and impactful way.

Big investments have already been made in quantum computing, as countries and companies battle to create the first quantum supercomputer, so they can harness the power of this awesome technology. The World Economic Forum has also recognised the important role that this technology will play in our future, and has a dedicated Global Future Council to drive collaboration between public and private sector organisations engaged in the development of Quantum Computing. Although its unlikely to result in any overnight miracles, its understandable that many are thinking about whether these huge efforts and investments can be turned towards the mutual challenge we face in finding a solution to the Covid-19 pandemic.

There are already some ground-breaking use-cases for quantum computing within the healthcare industry. Where in the past some scientific breakthroughs such as the discovery of penicillin came completely by accident, quantum computing puts scientists in a much stronger position to find what they were looking for, faster. Quantum raises capacity to such a high degree that it would be possible to model penicillin using just a third of the processing power a classical computer would require to do the job meaning it can do more with less, at greater speed.

In the battle against Covid-19, the US Department of Energys Oak Ridge National Laboratory (ORNL) is already using quantum supercomputers in its search for drug compounds that can treat the disease. IBM has also been using quantum supercomputers to run simulations on thousands of compounds to try and identify which of them is most likely to attach to the spike that Covid-19 uses to inject genetic material into healthy cells, and thereby prevent it. It has already emerged with 77 promising drugs that are worth further investigation and development progress that would have taken years if traditional computing power had been used.

Other businesses are likely to be keen to follow in the footsteps of these examples, and play their own part in dealing with the crisis, but to date its only been the worlds largest organisations that have been using quantum power. At present, many businesses simply dont have the skills and resources needed to fabricate, verify, architect and launch a large-scale quantum computer on their own.

It will be easier to overcome these barriers, and enable more organisations to start getting to work with quantum computing, if they open themselves up to collaboration with partners, rather than trying to go it alone. Instead of locking away their secrets, businesses must be willing to work within an open ecosystem; finding mutually beneficial partnerships will make it much more realistic to drive things forward.

The tech giants have made a lot of early progress with quantum, and partnering with them could prove extremely valuable. Google, for example, claims to have developed a machine that can solve a problem in 200 seconds that would take the worlds fastest supercomputer 10,000 years imagine adding that kind of firepower to your computing arsenal. Google, IBM and Microsoft have already got the ball rolling by creating their own quantum partner networks. IBM Q and Microsoft Quantum Network bring together start-ups, universities, research labs, and Fortune 500 companies, enabling them to enjoy the benefits of exploring and learning together. The Google AI quantum initiative brings together strong academia support along with start-up collaboration on open source frameworks and tools in their lab. Collaborating in this manner, businesses can potentially play their own part in solving the Covid-19 crisis, or preventing future pandemics from doing as much damage.

Those that are leading the way in quantum computing are taking a collaborative approach, acknowledging that no one organisation holds all the answers or all the best ideas. This approach will prove particularly beneficial as we search for a solution to the Covid-19 crisis: its in everyones interests to find an exit to the global shutdown and build knowledge that means we are better-prepared for future outbreaks.

Looking at the bigger picture, despite all the progress that is being made with quantum, traditional computing will still have an important role to play in the short to medium term. Strategically, it makes sense to have quantum as the exploratory left side of the brain, while traditional systems remain in place for key business-as-usual functions. If they can think about quantum-related work in this manner, businesses should begin to feel more comfortable making discoveries and breakthroughs together. This will allow them to speed up the time to market so that ideas can be explored, and new ground broken, much faster than ever before and thats exactly what the world needs right now.

Spain Introduces the World’s First Quantum Phase Battery – News – All About Circuits

By now, were no stranger to the quantum computing hype. When (or rather, if) they are successfully developed and deliver on their promised potential, quantum computers will be able to solve problems and challenges that would otherwise require hundreds or thousands or more years for current classic computer technology to solve.

In what could be a massive step for quantum computing, researchers from the University of the Basque County claim to have developed the worlds first quantum phase battery.

Today, batteries are ubiquitous, with lithium-ion batteries being the most common out of them, although alternatives do exist. These batteries convert chemical energy into a voltage that can provide power to an electronic circuit.

In contrast, quantum technologies feature circuits based on superconducting materials through which a current can flow without voltage, therefore negating the need for classic chemical batteries. In quantum technologies, the current is induced from a phase difference of the wave function of the quantum circuit related to the wave nature of matter.

A quantum device that can provide a persistent phase difference can be used as a quantum phase battery and induce supercurrents in a quantum circuit, powering it.

This is what the researchers set out to achievecreating such a quantum devicebuilding on an idea first conceived in 2015 by Sebastian Bergeret from the Mesoscopic physics group at the Materials Physics Center. Along with Francesco Giazotto and Elia Strambini from the NEST-CNR Institute, Pisa claims to have built the worlds first functional quantum phase battery.

Bergeret and Tokatlys idea, in short, involves a combination of superconducting and magnetic materials with an intrinsic relativistic effect known as spin-orbit coupling. On top of this idea, Giazotto and Strambini identified a suitable material combination that allowed them to fabricate their quantum phase battery.

Their quantum phase battery consists of an n-doped indium arsenide (InAs) nanowire, which forms the core of the cell, also known as the pile, and aluminum superconducting leads act as poles. The battery is charged by applying an external magnetic field, which can then be turned off.

If quantum batteries are ever to be realized, they could bring significant benefits over their chemical cousins. Among other things, quantum batteries could offer vastly better thermodynamic efficiency and ultra-fast charging times, making them perfect for next-gen applications like electric vehicles.

Professor tackles one more mystery about quantum mechanics and times flow – GeekWire

This computer-generated visualization shows the wavelike pattern of a quantum handshake between a hydrogen atom emitting energy and another atom receiving the energy. (J. Cramer and C. Mead via arXiv)

The University of Washington physicist whoonce ran a crowdfunded experiment on backward causationis now weighing in with a potential solution to one of the longest-running puzzles in quantum mechanics.

John Cramer, a UW physics professor emeritus, teamed up with Caltech electrical engineer and physicist Carver Mead to put forward an explanation for how the indefinite one-and-zero, alive-and-dead state of a quantum system gets translated into a definite observation a phenomenon known as wave function collapse.

Up to now, the mechanism behind wave function collapse has been considered a mystery that is disconnected from established wave mechanics. The result has been that a large number of attempts to explain it have looked elsewhere, Cramer told GeekWire in an email.

In our work, we have discovered that wave function collapse, at least in a simple case, is implicit in the existing formalism, he said, as long as one allows the use of advanced as well as retarded electromagnetic potentials.

In other words, the explanation requires accepting the possibility that time can flow backward as well as forward. And for some physicists, that might be too big of a quantum leap.

Most people just dont like the idea of having the kind of time symmetry that sort of implies that time isnt strictly speaking a one-way street, Cramer acknowledged during a phone interview.

Nevertheless, the idea is getting traction. A math-heavy research paper laying out the concept has been submitted to the open-access journal Symmetry, and Cramer said theres a good chance itll be accepted for publication now that he and Mead have addressed questions raised in peer review.

Were about to send a revised version of the paper back to the journal, he said.

The concept includes elements from what Cramer calls the Transactional Interpretation of quantum mechanics, which he laid out in a 2016 book called The Quantum Handshake. That interpretation, which Mead fleshed out in subsequent work, puts a new spin on the interaction between quantum systems.

Most physicists visualize the emission of electromagnetic energy from an atom in the form of particles namely, photons. But in Cramers interpretation, the energy transfer between atoms is a two-way transaction involving waves rather than particles. One set of waves spreads out from the source to interact with another set of time-reversed confirmation waves from the destination. Interactions between the forward-time waves and the backward-time waves quickly determine where the energy ends up, Cramer said.

The idea in the Transactional Interpretation is that youre using it as a sort of time-symmetric situation, in which its OK to have things going backward in time as well as forward in time, in the limited case where youre doing this handshake, he said.

If time reversal actually exists, would that open the door to the kind of time travel seen in movies such as Back to the Future? Unfortunately for Doc Brown, Mother Nature is very clever about not letting you in on the action, Cramer said. The time symmetry effect makes the equations work, but it wont show up in observations of the energy transfer.

That was also the case five years ago for Cramers retrocausality experiments. The interference patterns that he was hoping would provide the crucial evidence for backward causation ended up canceling each other out.

Nature is sending messages faster than light and backwards in time, but shes not letting you in on the action, Cramer said. Its blocked by this process.

In their research paper, the two physicists consider only the case of energy transfer between two hydrogen atoms, but Cramer said the concept could be extended to multiple atoms in a system.

Is there any way to prove or disprove the seemingly way-out interpretation put forward by Cramer and Mead? Thats tricky:By definition, an interpretation for quantum mechanics is judged by how well it matches up with the mathematics that underlie well-known quantum phenomena.

What you should do is see whether your interpretation can explain as many experiments as possible, Cramer said. My Transactional Interpretation explains more than 26 different quantum optics experiments in great detail how the handshakes work in order to make whats observed in the experiments come out.

He hasnt yet found an experiment that rules out the interpretation, but acknowledges that there are probably a lot more experiments left to check.

Cramer is particularly interested inan experiment known as TEQ, which stands for TEsting the large-scale limit of Quantum mechanics. The experiment has won a 4.4 million ($5 million) grant from the European Commission, and wasfeatured last week in The New York Times Magazine.

TEQs researchers aim to determine the value of a term that they think should be added to the Schrdinger Equation, which describes the wave function of a quantum system. The extra term would describe objectively how the wave function collapses, independently of any observers.

Cramer said TEQ may not turn out the way itsbackers expect.

What we demonstrated here is the mechanism by which the wave function does collapse, he said. And that means, in fact, that those experimenters will be wasting their time and their euros doing that measurement, because theyre almost certain to find that theres no such term.

This Is the First Universal Language for Quantum Computers – Popular Mechanics

Przemyslaw Klos / EyeEmGetty Images

A quantum computing startup called Quantum Machines has released a new programming language called QUA. The language runs on the startups proprietary Quantum Orchestration Platform.

Quantum Machines says its goal is to complete the stack that includes quantum computing at the very bottom-most level. Yes, those physical interactions between quantum bits (qubits) are what set quantum computers apart from traditional hardwarebut you still need the rest of the hardware that will turn physical interactions into something that will run software.

And, of course, you need the software, too. Thats where QUA comes in.

The transition from having just specific circuitsphysical circuits for specific algorithmsto the stage at which the system is programmable is the dramatic point, CEO Itavar Siman told Tech Crunch. Basically, you have a software abstraction layer and then, you get to the era of software and everything accelerated.

The language Quantum Machine describes in its materials isnt what you think of when you imagine programming, unless youre a machine language coder. Whats machine language? Thats the lowest possible level of code, where the instructions arent in natural or human language and are instead in tiny bits of direct instruction for the hardware itself.

Coder Ben Eater made a great video that walks you through a sample program written in C, which is a higher and more abstract language, and how that information translates all the way down into machine code. (Essentially, everything gets much messier and much less readable to the human eye.)

This content is imported from YouTube. You may be able to find the same content in another format, or you may be able to find more information, at their web site.

Machine code acts as a reminder that, on a fundamental level, everything inside your computer is passing nano-Morse code back and forth to do everything you see on the screen as well as all the behind the scenes routines and coordination. Since quantum computers have a brand new paradigm for the idea of hardware itself, theres an opening for a new machine code.

Quantum Machines seems to want to build the entire quantum system, from hardware to all the software to control and highlight it. And if that sounds overly proprietary or like some unfair version of how to develop new technology, we have some bad news for you about the home PC wars of the 1980s or the market share Microsoft Windows still holds among operating systems.

By offering a package deal with something for everyone when quantum computing isnt even a twinkle in the eye of the average consumer, Quantum Machines could be making inroads that will keep it ahead for decades. A universal language, indeed.

QUA is what we believe the first candidate to become what we define as the quantum computing software abstraction layer, Sivan told TechCrunch. In 20 years, we might look back on QUA the way todays users view DOS.

Universal Quantum raises $4.5 million to build a large-scale quantum computer – VentureBeat

Universal Quantum has raised $4.5 million as it emerges from stealth with plans to build a practical quantum computer it claims will be far more powerful than versions currently being developed by competitors.

Investors in this early-stage funding round include Hoxton Ventures, Village Global, Propagator VC, Luminous VC, and 7percent. Universal Quantum also disclosed that it has officially been spun out of the University of Sussex in the United Kingdom, where Professor Winfried Hensinger and Dr. Sebastian Weidt founded it in 2018.

Hensinger said the company is on target to build the worlds first large-scale quantum computer, using a pioneering approach developed at the university. If the company makes good on that promise, this next-generation computing architecture would have an impact on more industries and much sooner than many experts have generally predicted.

Its a really exciting next step, Hensinger said. Ive worked on this for 20 years as a university professor, and now we go on to actually building something useful, which is probably going to change the world.

Universal Quantum joins an expanding range of companies and institutions trying to develop quantum computing, which seeks to replace traditional computing architecture. Processing in current computing systems occurs in a binary state. Quantum computing, by contrast, is an atomic-level system in which the processing can occur in multiple states simultaneously. These are referred to as quantum bits or qubits.

Quantum computing has slowly moved beyond the labs, thanks to milestones such as Googles claim that it achieved quantum supremacy last year. That means its quantum computer performed a task that would likely have been impossible using traditional computing systems. Meanwhile, IBM has for several years been expanding its Q Network that allows research and corporate partners access to its quantum machines to experiment via a cloud platform.

But the field still faces a number of fundamental scientific challenges when it comes to making quantum computing stable at a large enough scale to have a real impact.

The founders of Universal Quantum say theyre taking an approach to solving some of those issues that will allow them to build what they call a large-scale quantum computer. So what does that mean? The quantum computer Google built that claimed the supremacy milestone had 54 qubits. IBMs Q Network relies on a 53-qubit machine.

If you want to solve interesting problems, you cant just have 50 qubits, Hensinger said. You need probably around a few million, maybe even billions.

Hensinger is making the extraordinary claim that his companys technology will make that billions target feasible.

Among problems the company has overcome is one involving temperature. Quantum computers run extremely hot because they often use two laser beams targeting each qubit to keep them stable enough for processing calculations. A large-scale computer using this system would require millions of laser beams operating at extreme precision and would need to be cooled to -273 degrees Celsius.

Hensinger explained that in place of lasers, Universal uses an approach called trapped ions that relies on microwave and radio frequency technologies, similar to the type found today in mobile phones. The system results in fewer errors and generates far less heat than laser systems, he said. He projects this computer could operate at -200 degrees Celsius.

In addition, Universal Quantum is developing plans for a quantum computer that relies on ion-trapped chips and uses silicon. After experimenting with a wide range of materials, Hensinger said his team settled on silicon for its stability and practicality.

As is the case with microwave technology, using silicon will allow the company to leverage existing products and technology. It will also allow the team to recruit employees with skillsets in those areas, rather than having to train and develop workers using radically different materials and methods, he said.

All of those factors should allow the company to build its quantum computer, though the exact timing remains unclear. With the latest funding, Universal Quantum will continue building its quantum computing facility in Brighton while expanding its 10-person team.

Once the computer is operational, the company will pursue a model initially similar to IBMs by offering subscriptions to its machines through a cloud platform, Hensinger said.

Ethereum (ETH) Might Not have Quantum Resistance on its Roadmap, the QRL Team Reveals – Crowdfund Insider

The developers at Quantum Resistant Ledger (QRL), an externally audited enterprise-grade blockchain platform that claims to be secure against a potential (future) attack from quantum computers, stated that Ethereum (ETH) could go quantum computer resistant through a unique smart-contract.

The QRL team said that a project called EnQlave helps users secure their computers against a quantum computer attack. They pointed out that the Ethereum 2.0 fork will bring many improvements like sharding, zero-knowledge proofs (ZKPs), enhancing overall blockchain efficiency, and lower transaction fees.

They noted:

One of the biggest hindrances to blockchains right now thats affecting its adoption is its ability to scale. [We] think [the Ethereum 2.0 related upgrades] will help out quite a bitProof of stake, Ethereum is going there, and so are we [at QRL.] Transparency, trust, immutability, pseudonymity, security all these things are core tenets of blockchain.

They added:

When it comes to Ether, [Ethereums native token,] were soon going to have another option. And that option is to make it quantum secure, or not. But why quantum? Quantum computers are quite cool [even literally.] In 2016, the NIST or National Institute of Standards and Technology (in the US) initiated a process to solicit, evaluate, and standardize one or more quantum resistant public key cryptographic algorithms.

They explained that this was basically the NIST calling upon academics and the general public to write and propose new asymmetric or public key algorithms to be used in the post-quantum era (i.e. when quantum computers powerful enough to threaten or practically outperform existing binary computers have arrived).

The QRL team revealed that so far there have been 60 submissions, out of which 12 were reportedly broken and there were five withdrawals from the competition. There are currently two quantum-secure protocols in draft recommended state, the team revealed. One of these is called XMSS which is the underlying protocol used by QRL.

They confirmed that quantum computers are available right now. For instance, D-Wave has been manufacturing them since 1999, the team said. IBM has also been releasing more and more powerful quantum computers.

The QRL team noted that, in 2019, Google announced Quantum Supremacy which is defined as the construction of a device that can solve a problem or perform a function that would be unfeasible for any classical computer. Google was able to carry out a function in 200 seconds and based on their calculations, it would take a supercomputer 10,000 years to complete the same function, the QRL team revealed.

They added:

It appears that quantum resistance is not on the Ethereum roadmap, so this is where I think the QRL team can help. Project EnQlave is an Ethereum smart contract that creates a quantum secure safe to store your Ethereum cryptocurrency.[this means, that] using your browser, you can access your Ethereum and transfer funds into a quantum secure safe, all while staying on the Ethereum blockchain.

However, the cost associated with doing this is that every time a smart contract is called or invoked for this purpose (moving funds in and out of your EnQlave wallet), you would incur a gas (fee) charge from the Ethereum network, The gas charge price is set by ETH miners who are processing transactions on the worlds largest smart contract development platform.

Gas fees are a financial incentive for Ether miners to process users transactions.

The QRL team recommended:

Due to gas costs, EnQlave works best as a long-term, post-quantum secure storage solution. Its not something youd want to move your funds in and out of every day.

As of June 2020, EnQlave has been running on an internal test network (testnet) and the code is being audited.

As previously reported, many experts believe quantum computers could completely shatter the current Internet security systems protecting the Bitcoin (BTC) network, digital payments, and IoT devices.
