We all learn from early on that computers work with zeros and ones, also known as binary information. This approach has been so successful that computers now power everything from coffee machines to self-driving cars and it is hard to imagine a life without them.

Building on this success, todays quantum computers are also designed with binary information processing in mind. The building blocks of quantum computers, however, are more than just zeros and ones, explains Martin Ringbauer, an experimental physicist from Innsbruck, Austria. Restricting them to binary systems prevents these devices from living up to their true potential.

The team led by Thomas Monz at the Department of Experimental Physics at the University of Innsbruck, now succeeded in developing a quantum computer that can perform arbitrary calculations with so-called quantum digits (qudits), thereby unlocking more computational power with fewer quantum particles.

Although storing information in zeros and ones is not the most efficient way of doing calculations, it is the simplest way. Simple often also means reliable and robust to errors and so binary information has become the unchallenged standard for classical computers.

In the quantum world, the situation is quite different. In the Innsbruck quantum computer, for example, information is stored in individual trapped Calcium atoms. Each of these atoms naturally has eight different states, of which typically only two are used to store information. Indeed, almost all existing quantum computers have access to more quantum states than they use for computation.

The physicists from Innsbruck now developed a quantum computer that can make use of the full potential of these atoms, by computing with qudits. Contrary to the classical case, using more states does not make the computer less reliable. Quantum systems naturally have more than just two states and we showed that we can control them all equally well, says Thomas Monz.

On the flipside, many of the tasks that need quantum computers, such as problems in physics, chemistry, or material science, are also naturally expressed in the qudit language. Rewriting them for qubits can often make them too complicated for todays quantum computers. Working with more than zeros and ones is very natural, not only for the quantum computer but also for its applications, allowing us to unlock the true potential of quantum systems, explains Martin Ringbauer.

BASF looks to quantum computing to improve weather modeling – The Register

July 22, 2022 | Author: admin

A new quantum computing partnership could pave the way to more efficient climate change modeling.

BASF and French quantum computing startup Pasqal have linked arms in a move that will see the chemical giant use Pasqal's proprietary quantum tech to improve its ability to predict the weather.

BASF's chemicals are found in a variety of products and materials. One of its sectors involves a portfolio of farming optimization software that includes xarvio Field Manager, a crop optimization platform. BASF uses weather models to inform its software's crop growth simulations, pesticide drift and other metrics, and believes Pasqal's quantum systems could help.

Physics-based weather modeling is complicated. Wind data, heat transfer, solar radiation, humidity, topology, and other factors combine into complex nonlinear differential equations that need solving, Pasqal said.

"Pasqal aims to solve the [math] in a novel and more efficient way by implementing so-called quantum neural networks on its neutral atom quantum processors," the company said.

There's already a non-quantum model that does what Pasqal and BASF are aiming toward: Nvidia's Earth-2 supercomputer. As opposed to using quantum algorithms, Nvidia's climate prediction model relies on physics-informed neural networks, which are commonly used for weather and climate modeling.

Dr John Manobianco, senior weather modeler at BASF's agricultural solutions division, said BASF's work with Pasqal would help it simplify computational simulations "once quantum hardware matures to a point where we can actually leverage these algorithms."

Pasqal said the information it learns from the collaboration with BASF can "build a foundation for future extensions of Pasqal's methods to support climate modeling."

Benno Broer, chief commercial officer at Pasqal, told The Register that Pasqal's work with BASF will "parameterize, implement and test Pasqal's proprietary family of quantum algorithms for solving differential equations."

Pasqal's differential equation solving algorithm has also been used by BMW to reduce vehicle component testing time. Along with its partnerships with BASF and BMW, Pasqal also announced an agreement with Saudi Aramco in March, and claims Johnson & Johnson, LG, Airbus as other customers.

With BASF, Pascal's differentiable quantum circuit (DQC) algorithm will be turned to predicting weather patterns, which Broer said will lead to Pasqal being able to specialize its algorithm.

"We expect to be able to tailor [DQC algorithms] to model such patterns on multiple spatial and temporal scales, meaning both long-term and short-term, local and global patterns (including climate change patterns) and events," Broer said.

With recent climate events bad enough to knock Google and Oracle data centers offline in Britian and do lasting damage, faster and longer-term weather modeling is definitely needed.

Quantum: Claims Solving 3,854-Variable Optimization Problem in 6 Minutes for BMW – High-Performance Computing News Analysis | insideHPC – insideHPC

July 22, 2022 | Author: admin

LEESBURG, Va., July 20, 2021 Quantum Computing Inc. (QCI) today announced it has solved an optimization problem with over 3,800 variables in six minutes by applying a new quantum hardware technology called Entropy Quantum Computing (EQC) to the BMW Vehicle Sensor Placement challenge. The problem consisted of 3,854 variables and more than 500 constraints. In comparison, todays Noisy Intermediate Scale Quantum (NISQ) computers can process approximately 127 variables for a problem of similar complexity.

The 2021BMW GroupandAmazon Web Services (AWS)Quantum Computing Challenge included a Vehicle Sensor Placement use case that challenged participants to find optimal configurations of sensors for a given vehicle that would provide maximum coverage (i.e. detect obstacles in different driving scenarios) at minimum cost. Although QCI placed as a 2021 finalist, its 2022 acquisition of quantum photonics systems company QPhoton provided a powerful suite of new quantum hardware technologies, including EQC. As a result, QCI today presented BMW with a 2022 solution: a superior sensor configuration consisting of 15 sensors yielding 96% coverage using QCIs quantum hardware and software.

The EQC ran over 70x faster than QCIs 2021 hybrid DWave implementation. While the speed itself is notable, the stability of the system allowed the Company to run the problem repeatedly and iteratively, demonstrating its usefulness for business applications.

We are very proud to have achieved what we believe to be an important landmark result in the evolution of quantum, said Bob Liscouski, CEO of QCI. We believe that this proves that innovative quantum computing technologies can solve real business problemstoday. Whats even more significant is the complexity of the problem solved. This wasnt just a rudimentary problem to show that quantum solutions will be feasible someday; this was a very real and significant problem whose solution can potentially contribute to accelerating the realization of the autonomous vehicle industry today.

Historically, commercially-available QPU architectures have only been able to process problems with minimal variable sizes, due to the limited number of qubits available to represent problem variables. These systems also sometimes suffer from significant errors in processing as well as stability and calibration issues, further limiting their commercial viability in todays market. In contrast, QCIs EQC can process computations over a many-variable space, with coherence, thus providing powerful quantum solutions to real-world problems.

EQC operates on the most fundamental principles of quantum physics, especially its measurement postulate, wherein the wave function of a quantum system will collapse to a certain eigenstate due to its interaction with a measurement apparatus or, broadly speaking, the surrounding environment. However, while existing quantum computing architectures must operate on closed quantum systems under extreme requirements to calm the effects of the environment, EQC operates on open quantum systems, carefully coupling a quantum system to an engineered environment, so that its quantum state is collapsed to represent a problemsdesirable solution.

BREAKING: Carlsen Not To Defend World Title – Chess.com

July 20, 2022 | Author: admin

GM Magnus Carlsen will not defend his world championship title against GM Ian Nepomniachtchi next year. Carlsen announced his decision on a podcast on Tuesday. According to current regulations, FIDE Candidates tournament winner Nepomniachtchi will now play the world championship against Candidates runner-up GM Ding Liren.

"Ive spoken to people in my team, Ive spoken to FIDE, I spoke to Ian as well. The conclusion is very simple: Im not motivated to play another match," said Carlsen. "I dont have a lot to gain. I don't particularly like it, and although Im sure a match would be interesting for historical reasons, I dont have any inclinations to play and I will simply not play the match."

Carlsen thus confirmed the earlier doubts he had expressed on December 14, 2021 and later repeated: after playing five world championship matches, he is not enjoying them anymore.

"Its been an interesting ride since I decided to play the Candidates in 2013, which was to be honest on kind of a whim. I just decided it could be interesting, and ever since the World Championship title has given me a lot and opened a lot of doors, and Im happy about that. The matches themselves have been at times interesting, at times a little bit of fun."

The Norwegian star leaves the door open to return for a match one day, but it's not likely: "I dont rule out participation in the future, but I also wouldnt count on it."

Carlsen made his statements in the first episode of the new podcast "The Magnus Effect."

During the FIDE Candidates tournament, Carlsen had a meeting with FIDE's President Arkady Dvorkovich and Director-General Emil Sutovsky, which apparently didn't have enough effect to convince Carlsen to defend his title a fifth time.

Talking about this meeting in Madrid, Carlsen said: "I did not have any demands or suggestions for that meeting. They did have a couple of suggestions, but the gist of it was that I was there to tell them that I would not defend my title in the next WCC match."

Dvorkovich told Chess.com that he respects the world champion's decision and confirmed that according to the rules, there will now be a Ding-Nepomniachtchi match.

As it turned out, Carlsen never really changed his mind on a feeling he has had for a while. "Ultimately, the conclusion stands, one that Im pretty comfortable with, one that I thought a lot about for a long time now," he said. "I would say more than a year, probably a year and a half. Long before the last match."

It didn't help that Nepomniachtchi qualified for a second match with Carlsen, who had stated earlier that he preferred an opponent of the new generation, in particular GM Alireza Firouzja. "Four championships to fiveit didnt mean anything to me. It was nothing," said Carlsen in yesterday's podcast. "I was satisfied with the job I had done. I was happy I had not lost the match. But that was it."

Carlsen also repeated once again that he intends to continue playing, just not matches: "Just so there is no ambiguity here: Im not retiring from chess. Im going to be an active player. Im leaving later today to go to Croatia to play the Grand Chess Tour. From there on Im going to go to Chennai to play the Olympiad, which is going to be a lot of fun, and the Norwegian team is seeded as number four there. And to Miami which is going to be one of the real highlights of the yearthe FTX Crypto Cup which is going to be awesome. And right after that the Sinquefield Cup."

"There are a lot of feelings around mind right now that I have to deal with, said Ding in a first reaction to Chess.com. "But I am very excited about playing a world championship match to fight for the crown next year."

Calling from Barcelona, where Ding is staying at a friend's apartment, he revealed that he got Covid right after the Candidates tournament and, therefore, hasn't been able to fly back to China yet. Now fully recovered, he will travel back about two weeks from now. The Chinese player is surprised about Carlsen's decision:

"I knew he had doubts, but I expected him to play. But I understand it also. Being world champion means a lot of responsibilities; there are a lot of things to handle."

Ding pointed out the similarities with Yuzuru Hanyu, the Japanese figure skater who, also yesterday, announced retirement from competition but promised to pursue his goal in exhibitions instead.

The chess world has seen previous moments in history when the world champion did not defend his title. In 1946, GM Alexander Alekhine died as the reigning champion. A world championship tournament, organized two years later, was won by GM Mikhail Botvinnik. In 1975, GM Bobby Fischer could not agree with FIDE on the match format and lost his title to Candidates winner GM Anatoly Karpov.

In 1993, GM Garry Kasparov left FIDE and played a world championship under the Professional Chess Association instead. This led to a schism in the chess world that lasted until 2006, when GM Vladimir Kramnik won a reunification match with FIDE champion GM Veselin Topalov.

"It's not an ideal situation that the best player is not defending his title, and creating your own organization is also not great," said Ding, adding: "It's better for the fans if the best players fight for the world championship, and Magnus has, of course, been the best player throughout the years. We came to a new era."

Ding did say that he hopes Carlsen will "return one day" and felt that reaching the highest possible competition also gives himself a new responsibility: "I have to improve my English now!"

Rediscovery: Chess of the Wind | Sight and Sound – British Film Institute

July 20, 2022 | Author: admin

Sign up for Sight & Sounds Weekly Film Bulletin and more

News, reviews and archive features every Friday, and information about our latest magazine once a month.

A few years ago, at the University of Bologna, I accompanied an ageing filmmaker who had been offered a private tour of the vaults. Being the oldest university in Europe, it holds precious manuscripts from past centuries literally, the foundations of our civilisation. Among these is one of the first illustrated atlases in the world, which was laid out for the guest. Handling the book with white gloves, he gently browsed the pages with such absorption; it was as if he had finally found the meaning of this otherwise chaoticworld.

As he turned the pages in wonder, I was reminded of the reason for his visit: a celluloid atlas, mapping the uncharted territories of world cinema, was being drawn by Martin Scorseses World Cinema Foundation and Cineteca di Bologna. The ageing filmmaker was there to supervise the restoration of one of his films, unseen fordecades.

The World Cinema Project, soon to mark its 15th anniversary, painstakingly closes the gulf between past and present. It began as a side project of The Film Foundation (whose sole task was the restoration of American films) and spread its arms in the most universalist manner. The results have been staggering, bringing back to life films from Latin America, Asia and Africa. Some titles are now available to stream in the UK, in a collaboration between The Film Foundation and the streaming platformMubi.

Charting the lost continents of film often involves complex processes, coordinated between various institutions and archives, supported by filmmakers, historians, curators and adventurers. Sometimes the task is complicated further when the only material available is in appalling shape. In some cases, a positive print of the film (worse still, one with burned-in subtitles) is the only surviving element. A positive print of the Turkish film Law of the Border (1966) was the only known copy to survive the countrys 1980 coup, during which all other elements weredestroyed.

Thanks to one important sidebar of WCP, the African Film Heritage Project, we can now see, in impeccable restorations, films from Cameroon (Muna Moto, 1976), Ivory Coast (La Femme au couteau, 1969) and Morocco (Trances), among other countries. These are not just interesting examples of films from underrepresented countries they are glorious works of art. Trances (Ahmed El Maanouni, 1981), a film about music, features an opening sequence so thrillingly cut, the music so passionately performed and deeply felt, that it forces you to watch it standing up, as if at a real concert. Or take Med Hondos 1967 drama Soleil O (from Mauritania), which has all the intensity of looking directly into thesun.

If there is a single film that captures the excitement of this project (which so far has restored 47 titles from 27 countries), it is the Iranian Chess of the Wind (1976), directed by Mohammad Reza Aslani. A film about the transition from feudalism to modernity, a process riddled with corruption and duplicity, Chess of the Wind is a miniature of Iranian society in the 1970s, even if it is set at the beginning of the last century. Showing an acute understanding of the dynamics of that society, it also offers a premonition of the revolution to come. The final shot is a 50-year jump in time, which sees the camera pan above the house that is the storys backdrop to frame the skyline of modern-day Tehran, extending the decadence and intrigue beyond the walls to society as a whole. Like many great artists, Aslani understood the past, felt the present and saw thefuture.

A story of deceit and intrigue set in a feudal mansion following the death of a matriarch, Chess of the Wind focuses on the various plots to gain the deceaseds assets at any price, even murder. The sense of friction that builds through the film also existed in Iran. The same regressive elements forced the film into oblivion following its ill-fated premiere a faulty projector followed by a hostile press conference at the Tehran International Film Festival in 1976. Aslani, a son of the new world, his modernism a source of fear, was held back by the forces of the old world. After the 1979 revolution, most Iranian pre-revolutionary films were deemed pernicious to moral wellbeing and were consequently destroyed or locked away. For decades Chess of the Wind was not only unseen and largely forgotten but lost as a physical object. It became an invisible film, yet one with an underground, even mythicalreputation.

Now the myth is gone and we face the concrete beauty of the film. At the same time we are reminded of the surprises and revelations that await those yet to discover the ground-breaking movement in Iranian pre-revolutionary cinema known as cinema-ye motafavet (alternative cinema), sometimes referred to as the Iranian New Wave. Some of its key talents were uprooted, exiled, banned or retired by force in great numbers after 1979. (Aslani didnt make another feature-length fiction film until 32 yearslater.)

Such restoration undertakings reveal the talent not only of greats like Aslani but of a whole team whose contributions could otherwise not be fully understood. How else could one appreciate the work of cinematographer Houshang Baharloo, who lit several scenes with candlelight? The restoration has also renewed interest in the films composer, Sheyda Gharachedaghi, one of the most prolific female composers of the 60s and 70s. Her bold, extraordinary work with horn and percussion is a fresh reminder of how imaginative she was in blending her Viennese conservatoire education with Iranian instruments andsensibility.

Reactions to screenings of the restoration in 2020 were universally ecstatic. I have never seen so much artistic brilliance and inventiveness recognised so suddenly as in the case of Chess of the Wind a work of art dusted off after 50 years of neglect, now officially added to the atlas of worldcinema.

Quantum computing and its impact on cybersecurity [Q&A] – BetaNews

July 20, 2022 | Author: admin

Quantum computing with its vastly improved processing capability offers the chance of many positive developments in research and science. But it also represents a potential threat to our current encryption models.

How big is quantum's threat to cybersecurity? And should we be taking action on this now? We talked to Skip Sanzeri, QuSecure co-founder and COO, to find out.

BN: What are some of the main trends around quantum computing development?

SS: The quantum computing industry is evolving rapidly. Just a few years ago we were struggling to find companies that had more than a few dozen qubits and now we are in the 100-qubit era. Companies such as IBM, IonQ, Google, and PsiQuantum are talking about having a thousand or more qubits by mid-decade. If coherence continues to advance and noise can be reduced, these systems will be even more powerful. The promise of quantum computing, due to the exponential nature of qubits in superposition, can do amazing things for society -- but job one is cybersecurity.

With the advent of quantum computing upon us, the potential for many positive enhancements to our society may be forthcoming, including algorithms to cut through global emissions and quantum chemistry for personalized medicine. At the same time, tens of billions of dollars are being spent by foreign nations to develop quantum computers (some of which have been openly declared as 'weaponized'). A quantum computer with approximately 4,000 qubits will be able to break RSA 2048 which is the primary algorithm that we rely on to keep the world's data safe on the internet. So, we should prepare for the possibility that the first use of quantum computing may be for harm rather than good.

BN: Why is the need for action now when we know quantum computers are years away?

SS: Store now, decrypt later attacks are the biggest reason to start upgrading networks and communications to post-quantum cybersecurity (PQC). Foreign nation states are stealing data every second of the day. This data is harvested and stored on computers waiting to be decrypted. Quantum computers will be able to crack encryption (proven mathematically by Shores Algorithm) once we reach the scale of around 4,000 qubits. We refer to this as 'Q-Day.' So, all data that is encrypted with current, non-PQC is at risk today of a quantum computer decrypting it in the future. For example, if a quantum computer with enough power to crack encryption is developed in five years, data stolen today would still be very valuable if it has 10, 20, or more years of shelf life. National security secrets, bank account information, and electronic health records may have data security requirements of up to 75 years. Making matters worse, many experts estimate that changing our current encryption across an enterprise or government agency could take as long as 10 years. Adding this to the shelf life of data means that there are 10 more years of exposed data which attackers can weaponize or use against us. In many cases, we are already behind.

Therefore, enterprises (and government already has mandates in place) should start looking very closely at PQC to encrypt current communications and data. If data is stolen but has quantum encryption, it will be safe for decades after Q-Day.

BN: What are the main challenges around addressing the post-quantum cyber threat?

SS: There are a variety of challenges to overcome when thinking about how organizations can become quantum resilient.

First, any change is difficult. Moving from older, legacy systems to newer technologies takes a great deal of planning, time and resources in order to not disrupt operations. Therefore, any upgrades, especially to cybersecurity, need to be backwards compatible so that the upgrade process can move more efficiently.

Second, cutting-edge technology always comes with risk. Betting on new technologies requires significant risk assessment to ensure that upgrades are carefully planned, and best-of-breed vendors are chosen. Using standards-based technologies such as the algorithms that NIST is recommending will help reduce risk. Also looking for companies that have referenceable clients, federally approved credentials, post-quantum cybersecurity, and successful implementations will reduce risk.

BN: What are some of the things organizations should look for in a PQC solution to best protect their data?

SS: Enterprises and government agencies need to look for solutions that are standards-based, backwards compatible, and have cryptographic agility. Using NIST algorithms helps satisfy standards risk. Selecting vendors that can transfer between existing systems and protocols to newer post-quantum protocols is vital so that companies dont have to rip and replace software, which causes disruption and risk. Cryptographic agility means that implementations can use a variety of cryptographic standards such as any of the NIST finalists, which further means that an organization can choose its cryptography versus being locked into just one type of cryptography due to a given vendors choice. By finding a partner like QuSecure that has an adaptive orchestrated solution with continuous availability that standardizes on all the NIST finalists, an organization can know that they have optimized their choice.

BN: There seem to be multiple options in terms of PQC solutions, which are the most optimal and why?

SS: A variety of vendors are coming on scene to help meet this massive upgrade need. There are some solutions that focus on Quantum Key Distribution (QKD). QKD is the idea that you can use two devices to transmit keys via entanglement making the transmission theoretically un-spyable, but it is currently severely range-limited. It is currently only useful for highly specific applications and requires significant scientific breakthroughs to make it applicable to larger networks. Some vendors offer quantum random number generation (ORNG), which serves generally random numbers for use in cryptographic keys. This solves the threat of pseudo random keys (programmatically generated random numbers, which is the standard today) being reverse engineered, but QRNG alone does not address the threat posed to public key cryptography by Shors Algorithm attacks.

Other vendors have teams of mathematicians that offer post quantum cryptographic algorithms, and these fall into two camps. The first is a class of proprietary cryptographic algorithms, and it is generally not recommended to implement non-standard algorithms in an enterprise or government environment. The second class is a handful of companies that have written NIST finalist algorithms and offer generally application specific implementations. Still other vendors offer consulting services for PQC implementation.

Optimally an organization should find the right mix of post-quantum cybersecurity software, hardware and services, and ideally utilize a vendor that provides for quantum orchestration across the enterprise to all nodes, communications and data. Features such as PQC policy management, key orchestration and backwards compatibility are elements that every organization should review so that implementation is seamless and much easier.

Pasqal, BASF aim to improve weather modeling with quantum computing – VentureBeat

July 20, 2022 | Author: admin

Paris-based Pasqal, a full-stack neutral atom quantum computing provider, and BASF, the multinational chemical juggernaut, are announcing a partnership focused on weather modeling and other computational fluid-dynamics applications. That area of problem-solving relies on solving complex nonlinear differential equations, a task for which, it turns out, Pasqals hardware and algorithms are especially well-suited.

VentureBeat spoke with Benno Broer, Pasqals chief commercial officer. Broer was CEO of Qu & Co. which was focused on quantum algorithms and software, and which merged with Pasqal in January of this year.

Broer said that Pasqals hardware platform implements qubits (quantum bits), using individually trapped atoms that are manipulated with laser beams, and that the company produces 100-qubit systems today. The neutral atom platform supports an analog mode, which enables addressing all of those qubits concurrently, thereby enabling quantum entanglement, where multiple qubits act as a single system and influence each other.

Building on this, Pasqals algorithm technology can implement quantum neural networks, the quantum computing equivalent of physics-informed neural networks (PINNs), a subset of physics-informed machine learning (PIML). In the PIML world, models can be trained using a combination of data and equations that describe the laws of physics underlying the modeled phenomena.

PIML techniques can be used to solve differential equations, which is the key to attacking computational fluid-dynamics applications, including weather modeling. According to Pasqals press release, BASF can then use parameters generated by the weather models to simulate crop yields and growth stages as well as to predict drift when applying crop protection products. The weather modeling further serves BASFs digital farming product portfolio, including an advanced crop optimization platform. This takes quantum computing down from the ivory tower, and applies it, quite literally, in the field.

Perhaps even more intriguing, Broer told VentureBeat the equations used to model short-term weather patterns and those for long-term climate modeling are, in fact, similar. Scaling up the time dimension can allow the technology being applied to weather modeling in the near future to be applicable to climate modeling later, and perhaps be used to mitigate the effects of climate change.

Given the heatwaves impacting so many regions across the world this week, the potential of quantum computing to help mitigate climate change impact is good news . And if were going to tech our way out of this (the phrase attributed to Kleiner Perkins chairman John Doerr), then an approach that combines quantum computing and physics-informed machine learning seems like a good start.

VentureBeat's mission is to be a digital town square for technical decision-makers to gain knowledge about transformative enterprise technology and transact. Learn more about membership.

Old computer technology points the way to future of quantum computing Hope Standard – Hope Standard

July 20, 2022 | Author: admin

Researchers have made a breakthrough in quantum technology development that has the potential to leave todays supercomputers in the dust, opening the door to advances in fields including medicine, chemistry, cybersecurity and others that have been out of reach.

In a study published in the journal Nature on Wednesday, researchers from Simon Fraser University in British Columbia said they found a way to create quantum computing processors in silicon chips.

Principal investigator Stephanie Simmons said they illuminated tiny imperfections on the silicon chips with intense beams of light. The defects in the silicon chips act as a carrier of information, she said. While the rest of the chip transmits the light, the tiny defect reflects it back and turns into a messenger, she said.

There are many naturally occurring imperfections in silicon. Some of these imperfections can act as quantum bits, or qubits. Scientists call those kinds of imperfections spin qubits. Past research has shown that silicon can produce some of the most stable and long-lived qubits in the industry.

These results unlock immediate opportunities to construct silicon-integrated, telecommunications-band quantum information networks, said the study.

Simmons, who is the universitys Canada Research Chair in silicon quantum technologies, said the main challenge with quantum computing was being able to send information to and from qubits.

People have worked with spin qubits, or defects, in silicon before, Simmons said. And people have worked with photon qubits in silicon before. But nobodys brought them together like this.

Lead author Daniel Higginbottom called the breakthrough immediately promising because researchers achieved what was considered impossible by combining two known but parallel fields.

Silicon defects were extensively studied from the 1970s through the 90s while quantum physics has been researched for decades, said Higginbottom, who is a post-doctoral fellow at the universitys physics department.

For the longest time people didnt see any potential for optical technology in silicon defects. But weve really pioneered revisiting these and have found something with applications in quantum technology thats certainly remarkable.

Although in an embryonic stage, Simmons said quantum computing is the rock n roll future of computers that can solve anything from simple algebra problems to complex pharmaceutical equations or formulas that unlock deep mysteries of space.

Were going to be limited by our imaginations at this stage. Whats really going to take off is really far outside our predictive capabilities as humans.

The advantage of using silicon chips is that they are widely available, understood and have a giant manufacturing base, she said.

We can really get it working and we should be able to move more quickly and hopefully bring that capability mainstream much faster.

Some physicists predict quantum computers will become mainstream in about two decades, although Simmons said she thinks it will be much sooner.

In the 1950s, people thought the technology behind transistors was mainly going to be used for hearing aids, she said. No one then predicted that the physics behind a transistor could be applied to Facebook or Google, she added.

So, well have to see how quantum technology plays out over decades in terms of what applications really do resonate with the public, she said. But there is going to be a lot because people are creative, and these are fundamentally very powerful tools that were unlocking.
