TEL AVIV, Israel--(BUSINESS WIRE)--Classiq, the leader in quantum computing software, today announced the Classiq Coding Competition, rewarding those that create highly-efficient quantum circuits to solve important real-world problems. The Classiq Coding Competition is the first competition focused on quantum efficiency. Quantum computers have limited resources, so building compact, optimized solutions that can make maximum use of those resources is critical.

Creating efficient quantum algorithms is part engineering, part art. The Classiq Coding Competition is a call to the worlds quantum software community to showcase their talents and demonstrate how quantum computing can take humans to new heights, said Classiq CEO Nir Minerbi. Efficient circuits enhance the ability of any quantum computer to solve important problems.

The Classiq Coding Competition will consist of four problems and will award 17 cash prizes totaling $25,000. The top entry for each of the four problems will receive $3,000, while $1,500 and $500 will be awarded for the second and third places in each problem. Classiq will also award several $1,000 prizes to creators of the best innovative solutions as well as to the most promising youth participants under the age of 18. In addition, first-place winners will be profiled in The Quantum Insider.

A panel of esteemed judges will determine the winners. The judges are:

For some problems, the winning entries will be those that create a working circuit with the fewest two-qubit gates, while others will seek to minimize the circuit depth. Classiq will reveal the Classiq Coding Competition winners in mid-June.

You would be surprised how much can be achieved with compact, efficient circuits, said Minerbi. The onboard computer used in the Apollo 11 space mission got a man to the moon using just 72 kilobytes of ROM. Quantum computing is taking off, and the need to create elegant and efficient quantum algorithms will exist for years to come. Organizations that manage to fit larger problems into available computers will reap their quantum benefits sooner than others.

Stephen Hawking once suggested Albert Einsteins assertion that God does not play dice with the universe was wrong. In Hawkings view, the discovery of black hole physics confirmed that not only did God play dice, but that he sometimes confuses us by throwing them where they cant be seen.

Are we here by chance or design?

A more pragmatic approach to the question, considering the subject matter, would be to assume that all answers are correct. In fact, thats the basis of quantum physics.

Heres the simplest explanation of how it all works that youll ever read: imagine flipping a coin and then walking away secure in the knowledge that it landed on heads or tails.

If we look at the entire universe and start zooming in until you get down to the tiniest particles, youll see the exact same effect in their interactions. Theyre either going to do one thing or another. And, until you observe them, that potential remains.

With all that potential out there in the universe just waiting to be observed, were able to build quantum computers.

However, like all things quantum, theres a duality involved in harnessing Gods dice for our own human needs. For every mind-blowing feat of quantum engineering we come up with just wait until you read about laser tweezers and time crystals we need some grounded technology to control it.

In reality, theres no such thing as a purely-quantum computer and there probably never will be. Theyre all hybrid quantum-classical systems in one way or another.

Lets start off with why we need quantum computers. Classical (or binary, as theyre often called) computers the kind youre reading this on complete goals by solving tasks.

We program computers to do what we want by giving them a series of commands. If I press the A key on my keyboard, then the computer displays the letter A on my screen.

Somewhere inside the machine, theres code telling it how to interpret the key press and how to display the results.

It took our species approximately 200,000 years to get that far.

In the past century or so, weve come to understand that Newtonian physics doesnt apply to things at very small scales, such as particles, or objects at particularly massive scales such as black holes.

The most useful lesson weve learned in our relatively recent study of quantum physics is that particles can become entangled.

Quantum computers allow us to harness the power of entanglement. Instead of waiting for one command to execute, as binary computers do, quantum computers can come to all of their conclusions at once. In essence, theyre able to come up with (nearly) all the possible answers at the same time.

The main benefit to this is time. A simulation or optimization task that might take a supercomputer a month to process could be completed in mere seconds on a quantum computer.

The most commonly cited example of this is drug discovery.In order to create new drugs, scientists have to study their chemical interactions. Its a lot like looking for a needle in a never-ending field of haystacks.

There are near-infinite possible chemical combinations in the universe, sorting out their individual combined chemical reactions is a task no supercomputer can do within a useful amount of time.

Quantum computing promises to accelerate these kinds of tasks and make previously impossible computations commonplace.

But it takes more than just expensive, cutting-edge hardware to produce these ultra-fast outputs.

Hybrid quantum computing systems integrate classical computing platforms and software with quantum algorithms and simulations.

And, because theyre ridiculously expensive and mostly experimental, theyre almost exclusively accessed via cloud connectivity.

In fact, theres a whole suite of quantum technologies out there aside from hybrid quantum computers, though theyre the technology that gets the most attention.

In a recent interview with Neural, the CEO of SandboxAQ (a Google sibling company under the Alphabet umbrella), Jack Hidary, lamented:

For whatever reason, the mainstream media seems to only focus on quantum computing.

There are also quantum sensing, quantum communications, quantum imaging, and quantum simulations although, some of those overlap with quantum hybrid computing as well.

The point is, as Hidary also told Neural, were at an inflection point. Quantum tech is no longer a far-future technology. Its here in many forms today.

But the scope of this article is limited to hybrid quantum computing technologies. And, for that, were focused on two things:

There are two kinds of problems in the quantum computing world: optimization problems and the kind that arent optimization problems.

For the former, you need a quantum annealing system. And, for everything else, you need a gate-based quantum computer probably. Those are still very much in the early stages of development.

But companies such as D-Wave have been building quantum annealing systems for decades.

Heres how D-Wave describes the annealing process:

The systems starts with a set of qubits, each in a superposition state of 0 and 1. They are not yet coupled. When they undergo quantum annealing, the couplers and biases are introduced and the qubits become entangled. At this point, the system is in an entangled state of many possible answers. By the end of the anneal, each qubit is in a classical state that represents the minimum energy state of the problem, or one very close to it.

Heres how we describe it here at Neural: have you ever seen one of those 3-D pin art sculpture things?

Thats pretty much what the annealing process is. The pin art sculpture thing is the computer and your hand is the annealing process. Whats left behind is the minimum energy state of the problem.

Gate-based quantum computers, on the other hand, function entirely differently. Theyre incredibly complex and there are a number of different ways to implement them but, essentially, they run algorithms.

These include Microsofts new cutting-edge experimental system which, according to a recent blog post, is almost ready for prime time:

Microsofts approach has been to pursue a topological qubit that has built-in protection from environmental noise, which means it should take far fewer qubits to perform useful computation and correct errors. Topological qubits should also be able to process information quickly, and one can fit more than a million on a wafer thats smaller than the security chip on a credit card.

And even the most casual of science readers have probably heard about Googles amazing time crystal breakthrough.

Last year, here on Neural, I wrote:

Googles time crystals could be the greatest scientific achievement of our lifetimes.

A time crystal is a new phase of matter that, simplified, would be like having a snowflake that constantly cycled back and forth between two different configurations. Its a seven-pointed lattice one moment and a ten-pointed lattice the next, or whatever.

Whats amazing about time crystals is that when they cycle back and forth between two different configurations, they dont lose or use any energy.

Heck, even D-Wave, the company that put quantum annealing on the map, has plans to introduce cross-platform hybrid quantum computing to the masses with an upcoming gate-based model of its own.

The quantum computing industry is already thriving. As far as were concerned here at Neural, the mainstream is just now starting to catch a whiff of what the 2030s are going to look like.

As Bob Wisnieff, CTO of IBM Quantum, told Neural back in 2019 when IBM unveiled its first commercial quantum system:

We get to be in the right place at the right time for quantum computing, this is a joy project This design represents a pivotal moment in tech.

According to Wisnieff and others building the hybrid quantum computer systems of tomorrow, the timeline from experimental to fully-implemented is very short.

Where annealing and similar quantum optimization systems have been around for years, were now seeing the first generation of gate-based models of quantum advantage come to market.

You might remember reading about quantum supremacy a few years back. Quantum advantage is the same thing but, semantically speaking, its a bit more accurate. Both terms represent the point at which a quantum computer can perform a given function in a reasonable amount of time that would take a classical computer too long to do.

The reason supremacy quickly went out of favor is because quantum computers rely on classical computers to perform these functions, so it makes more sense to say they give an advantage when used in tandem. Thats the very definition of hybrid quantum computing.

As for whats next? Its unlikely youll see a ticker-tape parade for quantum computing any time soon. There wont be an iPhone of quantum computers, or a cultural zeitgeist surrounding the launch of a particular processor.

Instead, like all great things in science, over the course of the next five, 10, 100, and 1,000 years, scientists and engineers will continue to pass the baton from one generation to the next as they stand upon the shoulders of giants to see into the future.

Thanks to their continuing work, in our lifetimes were likely to see vast improvements to power grids, a resolution to mass scheduling conflicts, dynamic shipping optimizations, pitch-perfect quantum chemistry simulations, and even the first inklings of far-future tech such as warp engines.

These technological advances will improve our quality of life, extend our lives, and help us to reverse human-caused climate change.

Hybrid quantum computing is, in our humble opinion here at Neural, the single most important technology humankind has ever endeavored to develop. We hope youll stick with us as we continue to blaze a trail of coverage at the frontier of this new and exciting realm of engineering.

Quantum computers will eventually break much of todays encryption, and that includes the signing algorithm of Bitcoin and other cryptocurrencies. Approximately one-quarter of the Bitcoin ($168bn) in circulation in 2022 is vulnerable to quantum attack, according to a study by Deloitte.

Cybersecurity specialist Itan Barmes led the vulnerability study of the Bitcoin blockchain. He found the level of exposure that a large enough quantum computer would have on the Bitcoin blockchain presents a systemic risk. If [4 million] coins are eventually stolen in this way, then trust in the system will be lost and the value of Bitcoin will probably go to zero, he says.

Todays cryptocurrency market is valued at approximately $3trn and Bitcoin reached an all-time high of more than $65,000 per coin in 2021, making crypto the best-performing asset class of the past ten years, according to Geminis Global State of Crypto report for 2022. However, Bitcoins bumpy journey into mainstream investor portfolios coincides with major advances in quantum computing.

Most encryption relies on the relationship between public and private keys, which is called asymmetric cryptography. Quantum-vulnerable Bitcoins include those created before 2010 when public keys had not been hashed into a different and safer format. Also at risk are Bitcoin addresses that have been already used once and have therefore become visible on the blockchain. There are four million Bitcoin addresses that could in theory be hacked by a quantum computer large enough to derive the corresponding private key to unlock and transfer the value to another address. This is known as a storage attack.

The second kind of attack a transit attack attacks Bitcoin transactions in transit. In contrast to the storage attacks, where only a subset of addresses is vulnerable, all transactions are vulnerable.

In January 2022, a team at Sussex University spin-out company Universal Quantum published research on transit attacks, which calculated that it would require a quantum computer with a 1.9 billion qubit-capacity to break Bitcoins encryption in the required ten-minute window (this is the time taken for a Bitcoin to be mined). Even at 317 million qubits it would take an hour and 13 million qubits for a day. For context, IBMs superconducting quantum computer currently has a 127-qubit processor.

Cybersecurity is top of mind for those within the quantum community, but many industry insiders, including Barmes, believe there is not enough communication between the quantum computing community and the Bitcoin community to ensure future cybersecurity on the Bitcoin blockchain. There are a lot of statements made from either community which indicates a lack of understanding of the other side, he says.

Barmes believes that as long as cryptocurrencies migrate on time (to post-quantum cryptography) then everything should be fine. It is not too late to migrate, but such a migration takes time, so waiting until the last moment might turn out to be too late, he says. The exact moment when it becomes too late is, of course, unknown.

The blockchain presents a unique challenge for quantum-safe cryptography because of its decentralised nature and the complications in governance structures that this poses. Achieving this consensus is extremely difficult, so the governance issues are possibly equal to the complexities of the technical problems agreement takes much more time than people think, says Barmes. While not enough is being done on technical solutions, too little attention is also given to governance issues, he adds.

Barmes is advocating awareness of the issues as the first stage in addressing the problem. Then, very technical people need to come up with published and demonstratable solutions, not just speculation, he adds.

For investors without a technical background, quantum security is a difficult topic to evaluate. Cryptocurrency projects should be more transparent about their plans to mitigate quantum risk, says Barmes. That will give investors the information they need in order to make decisions. The hope is that this transparency could encourage a more robust mitigation strategy.

While more mainstream investors may not be aware of the potential security issues arising from quantum computing advances on Bitcoin, Miko Matsumura, general partner at San Francisco-based Cryptos Capital, says most knowledgeable investors have priced in the risk of quantum cybersecurity breaches. He is not concerned about quantum computing risk because attackers have two ways to breach Bitcoin, neither one of which presents a catastrophe for the blockchain.

You could attack Bitcoins signing mechanism, which would create havoc during an attack, but the attack would be very visible, adds Matsumura. If such attackswere to take place, Satoshi [Bitcoins architect] had a plan, which was simply to hard fork Bitcoin (a complete protocol change leading to divergence from the original) and replace the signing mechanism.

On the point of consensus, Matsumura is much more buoyant than Barmes. Satoshi already wrote about what to do in case the signing algorithm was penetrated, so it is likely that the community would just agree to do what Satoshi proposed, he says.

On this more positive note, Duncan Jones, head of cybersecurity at Cambridge Quantum, says the conversation about risk needs to be more focused on how quantum technologies can enhance digital asset security. The focus is often on the threat from quantum computers, and yet blockchains face complex and sophisticated threats every day, he says. We can strengthen blockchains against some of these risks if we integrate quantum technology into the core of these systems.

This is a view reiterated by Charles Hayter, CEO and co-founder of CryptoCompare, who believes quantum computing cyber risk is not on the radar of the cryptocurrency investment community. The optimistic view is that quantum-safe cryptocurrency will solve the problems that arise and that is the reason that the community is not worried, he says. It is considered by many in the industry as like having to replace the engine on your car there is a solution.

Cryptography has always been a race against hackers and there have always been solutions along the way, says Hayter. As for quantum cybersecurity mitigation strategies on cryptocurrency exchanges, he believes it is far too early for quantum computing to be an issue.

Transitioning to post-quantum algorithms and conversations between the Bitcoin community and the quantum computing community will be key to mitigating the cybersecurity risk to cryptocurrency investment. As always, timelines around quantum computing appear to be vague, but nevertheless the time has come for Bitcoin investors to take note.

It could be right out of Back to the Future but a device known as a quantum memristor has been invented to open up the possibility of building a brainlike supercomputer. Lets call it Orac, Blakes 7 fans.

Detailing the creation of the first prototype of such a device in the journal Nature Photonics, Experimental photonic quantum memristor | Nature Photonics, scientists say the breakthrough could help combine quantum computing with artificial intelligence and the development of quantum neuromorphic computers.

A memristor or memory resistor is describedas a kind of building block for electronic circuits that scientists predicted roughly 50 years ago but created for the first time only a little more than a decade ago.

These components are essentially electric switches that can remember whether they were toggled on or off after their power is turned off. As such, they resemble synapsesthe links between neurons in the human brainwhose electrical conductivity strengthens or weakens depending on how much electrical charge has passed through them in the past.

In theory, memristors can act like artificial neurons capable ofboth computing and storing data. As such, researchers have suggested thatneuromorphiccomputer would perform well at running neural networks, which are machine-learning systems that use synthetic versions of synapses and neurons to mimic the process of learning in the human brain.

Using computer simulations, the researchers suggest quantum memristors could lead to an exponential growth in performance in a machine-learning approach known asreservoir computingthat excels at learning quickly.

Potentially, quantum reservoir computing may have aquantum advantageover classical reservoir computing, says study lead author Michele Spagnolo, a doctoral student in quantum physics at the University of Vienna.

The advantage of using a quantum memristor in quantum machine learning is the fact that the memristor, unlike any other quantum component, has memory, he adds.

Among the more profound benefits that quantum computers could be used for is to simulate quantum physical processes for much faster drug and material design; to accelerate AI development and to provide new levels of security and information communication. But they could also be used to break public-key encryptions, to amplify current AI risks at a faster pace, or be misused in biotechnology to design bio-weapons or other risks.

We now live in a Wright brothers moment in the history of quantum computing,Ibrahim Almosallam, a consultant for the Saudi Information Technology Company, writes atWorld Economic Review. When a commercial jet version arrives, it will deliver a new leap in information technology similar to what classical computation delivered in the 20th century, and, just like with any general-purpose technology such as the internet, electricity, and, for that matter, fire alongside great benefits, comes great risks.

Then theres more prosaic stuff like a super-AI creating the latest Pixar feature. This is where quantum can turbo-charge machine learning, improving the ability of AI to derive useful information from photos and videos, according to a recent report in the Harvard Business Review Quantum Computing for Business Leaders (hbr.org).

However, building and scaling a stable quantum computer is not easy. Photons and electrons are delicate; their behaviour defies our ingrained view of how the physical world operates, saysHBR.

One of the most formidable obstacles to building functional quantum computers is that qubits dont stick around very long, the article elaborates. Vibration, temperature, and other environmental factors can cause them to lose their quantum-mechanical properties, resulting in errors. Today, the rate at which errors occur in qubits limits the duration of algorithms that can be run.

Scientists are working to build environments in which many physical qubits act together to create error-protected logical qubits, which can survive for much longer periods of time long enough to support commercially viable applications.

Still, the most advanced quantum computers today have 50 to 100 physical qubits; it will most likely need ten times that to make a single error-protected logical qubit.

It is the state of flux (known assuperpositions) in which photons exist which causes the inherent instability of quantum systems. Superposition means they can essentially be located in two or more places at once (or spin in two opposite directions at the same time).

The breakthrough quantum memristor in the new study, as outlined by IEEE Spectrum, is a technique that relies on a stream of photons existing in superpositions where each single photon can travel down two separate paths laser-written onto glass. One of the channels in this single-qubit integrated photonic circuit is used to measure the flow of these photons, and this data, through a complex electronic feedback scheme, controls the transmissions on the other path, resulting in the device behaving like a memristor.

In other words, while memristive behavior and quantum effects are not expected to coexist, the researchers appear to have overcame this apparent contradiction by engineering interactions within their device to be strong enough to enable memristivity but weak enough to preserve quantum behaviour.

Taking another leap into the theoretical, this could also have implications for our understanding of what it means to live in the multiverse.

Stay with me here. Yes, the multiverse is currently in vogue among storytellers as a means to spin more canon fodder out of tired IP franchises. Looking at you directly Marvel and your upcomingDoctor Strange in the Multiverse of Madness. Even season 2 of Netflix comedy Russian Doll loops its protagonists back to 1982 and riffs on Back to the Future.

The multiverse as depicted in the movies, is a world full of endless potential; multiple parallel universes spinning in synchronicity; and the possibility of alternate, powerful, seemingly better versions of ourselves.

At Vox, a mathematical physicist at the California Institute of Technology, says this is possible in theory.

Spyridon Michalakis is no random boffin Im the science consultant forAnt-Manand I introduced the quantum realm [to Marvel], he explains.

Having established his credentials, Michalakis then explains that basically the multiverse is grounded in quantum mechanics.

Space and time are one single, singular construct, he explains in a 101 of Einsteins theory. Theres not like you have space and then time; itsspace X time.Moreover, quantum space time is a superposition: a quantum superposition of an infinite number of space times, all happening at the same time.

That word again: superposition.

This illusion basic physical reality is the fact that human beings have very specific points of view, ways of observing the superposition.

He makes this startling observation by mixing science with a cinematic metaphor.

The frame rate of the human mind is so low relative to the frame rate of the universe, he says. Lets say we only perceive 100 frames per second. We can be aware of our lives and choices we make, but then the frame rate of the universe (where you could be flicking between different timelines) is 40 orders of magnitude above that.

Were all trying to figure out the plot of the universe by just watching the beginning and the end of the movie, the first and last frame. Were just reconstructing the in-between the best we can. Thats where the multiverse hides; it hides there in between frames. Honestly, I think that the frame rate of the universe truly is infinite, not even finite, very, very large. And were so far away from that.

So that means were stuck in observing just one reality, not the multiplicity of them but we could if only we had a brain the size of a planet.

If only we could build one

The European Investment Bank (EIB) announced on Friday that it has granted 35M to IQM Quantum Computers for the development and commercialisation of its quantum processors. The development follows IQMs announcement in November of the opening of its first fabrication facility in Espoo, Finland.

The funding is part of the European Guarantee Funds venture debt product introduced to provide liquidity to small and medium-sized companies affected by the pandemic.

The European Investment Bank (EIB) is a long-term lending institution of the European Union owned by its Member States. It makes long-term finance available for sound investment in order to contribute toward EU policy goals.

Speaking on the development, EIB Vice-President Thomas Ostros, says, As we consider quantum computing as a sector of strategic importance, we are glad to support the Finland-based company IQM. With our financing, we not only sustain and create jobs within a highly innovative industry, but we also place ourselves squarely behind technological know-how. Europe has a strong tradition of quantum research, and funding IQM ensures that the results of this research will be put into practice in real-world innovations.

Founded in 2018 by Jan Goetz, Juha Vartiainen, Kuan Yen Tan, and Mikko Mottonen, IQM builds scalable hardware for universal quantum computers, focusing on superconducting technology.

The company provides on-premises quantum computers for supercomputing data centres and research labs, and offers full access to its hardware. For industrial customers, IQM delivers a quantum advantage through an application-specific, co-design approach.

As a spinoff of Aalto University and VTT Technical Research Centre of Finland, IQMs core technology builds upon decades of research from the world-renowned Quantum Computing and Devices (QCD) lab. This know-how is combined with the experience of renowned quantum computing experts from Bilbao, Munich, Zurich, Delft, and several other locations.

Additionally, IQM is building Finlands first commercial 54-qubit quantum computer with VTT, and an IQM-led consortium (Q-Exa) is building a quantum computer in Germany. The computer will be integrated into an HPC supercomputer to create an accelerator for future scientific research. IQM has over 160 employees with offices in Paris, Bilbao, Munich and Espoo.

EIB President Werner Hoyer says, Quantum computing is still at an early stage. However, it has the potential to revolutionise many sectors, from drug and vaccine development to cybersecurity. Given the scale of the potential impact, global competition in quantum computing is fierce. Ensuring that companies such as IQM are well-funded is key to positioning Europe as a technological leader worldwide.

IQM says that the initial tranche of the EIB funds will be used for expanding the facility, accelerating material research and developing quantum processors.

IQMs Chief Executive Jan Goetz says, Todays chips shortage has exposed just how dependent the world is on semiconductor manufacturers in Asia. Quantum processors give us an opportunity to learn from this and become self-reliant first, and a global provider for quantum chips in the future.

This EIB loan supports us in building more balanced and resilient quantum development in Europe. We are already working on the most advanced quantum technology in Europe and this loan will also help us create the next-generation European quantum ecosystem, adds Goetz.

Recently, IQM announced its open-source processor design software, KQCircuits, the Q-Exa project for quantum acceleration for HPC centres, and the opening of the quantum fabrication facility. With this funding, the company says it will have full control over quantum processor development and strengthen its European leadership.
