Theres quite a bit of ground standing between humanity and a working quantum computer, and experts are worried that Europe could be left behind as the US and China pour billions into the technology.

But one startup from the small German city of Ulm believes it can help smaller players with less capital to compete against the big guns of Google and IBM, by addressing one of the key technical challenges in building a useful quantum computer.

QC Design which is today coming out of stealth mode is building technology to help quantum hardware companies fast track a process known as error correction: the task of getting more qubits (the quantum equivalent of a bit a unit of information in classical computing) working together to scale up the power of these machines.

Companies like Paris-based PASQAL,UK-based Quantum Motion and Finnish IQM are all building their own approaches to quantum computers, trying to increase the number of qubits in their systems.

But scaling up the number of qubits isn't the only challenge. To begin solving complex problems like finding new drugs or useful materials quantum computer builders also have to create something called logical qubits.

In simple terms, a logical qubit is a combination of hundreds of qubits working together to facilitate complex quantum calculations. This is difficult to achieve due to the very delicate nature of qubits, which generally have to be chilled to extremely low temperatures to keep them stable, making them expensive and difficult to operate.

This is where error correction comes in, as researchers build systems that counteract the natural faults that qubits make (a goal in quantum computing known as fault tolerance). But theres a big talent shortage in this field and Europe is far behind in the race, according to QC Design founder Ish Dhand.

American companies were here first and lots of the top error correction researchers from Europe and elsewhere in the world work with these big North American companies, he says.

If you look at the companies that have blueprints and roadmaps to fault tolerance, these are predominantly North American companies. Even with the biggest companies in Europe which have really good physical qubits the roadmaps to fault tolerance are not yet there.

QC Design hopes it can level the playing field for smaller companies that can't hire the right kind of talent, by licensing them the technology they need to help them scale up their logical qubits.

This will be a mix of hardware architecture and software design, and Dhand tells Sifted that there are already around 50 quantum computing companies globally which could benefit from QC Designs architecture licences.

The company hasn't signed any clients yet, but says its opened early discussions with some quantum hardware builders.

The founder compares his company to an early-stage version of UK chip company ARM, which licences the IP for its chip architecture rather than making the chips itself.

Its just like ARM licences out designs the laptop that I'm talking from is an ARM-designed chip but ARM doesnt make any chips of their own. It's the designs that we licence out, says Dhand.

Comparisons to ARM are, of course, a little premature QC Design was founded in 2021 and employs 10 people. But the company did land pre-seed backing from deeptech investors Vsquared, Quantonation and Salvia last year, and could provide an important piece of the puzzle for companies trying to keep up with the best-funded players in quantum computing.

The startup using ARMs blueprint to give European quantum a fighting chance - Sifted

A University of Minnesota Twin Cities-led team has developed a new superconducting diode, a key component in electronic devices, that could help scale up quantum computers for industry use and improve the performance of artificial intelligence systems. Compared to other superconducting diodes, the researchers device is more energy efficient; can process multiple electrical signals at a time; and contains a series of gates to control the flow of energy, a feature that has never before been integrated into a superconducting diode.

The paper is published inNature Communications, a peer-reviewed scientific journal that covers the natural sciences and engineering.

A diode allows current to flow one way but not the other in an electrical circuit. Its essentially half of a transistor, the main element in computer chips. Diodes are typically made with semiconductors, but researchers are interested in making them with superconductors, which have the ability to transfer energy without losing any power along the way.

We want to make computers more powerful, but there are some hard limits we are going to hit soon with our current materials and fabrication methods, said Vlad Pribiag, senior author of the paper and an associate professor in the University of Minnesota School of Physics and Astronomy. We need new ways to develop computers, and one of the biggest challenges for increasing computing power right now is that they dissipate so much energy. So, were thinking of ways that superconducting technologies might help with that.

The University of Minnesota researchers created the device using three Josephson junctions, which are made by sandwiching pieces of non-superconducting material between superconductors. In this case, the researchers connected the superconductors with layers of semiconductors. The devices unique design allows the researchers to use voltage to control the behavior of the device.

Their device also has the ability to process multiple signal inputs, whereas typical diodes can only handle one input and one output. This feature could have applications in neuromorphic computing, a method of engineering electrical circuits to mimic the way neurons function in the brain to enhance the performance of artificial intelligence systems.

The device weve made has close to the highest energy efficiency that has ever been shown, and for the first time, weve shown that you can add gates and apply electric fields to tune this effect, explained Mohit Gupta, first author of the paper and a Ph.D. student in the University of Minnesota School of Physics and Astronomy. Other researchers have made superconducting devices before, but the materials theyve used have been very difficult to fabricate. Our design uses materials that are more industry-friendly and deliver new functionalities.

The method the researchers used can, in principle, be used with any type of superconductor, making it more versatile and easier to use than other techniques in the field. Because of these qualities, their device is more compatible for industry applications and could help scale up the development of quantum computers for wider use.

Right now, all the quantum computing machines out there are very basic relative to the needs of real-world applications, Pribiag said. Scaling up is necessary in order to have a computer thats powerful enough to tackle useful, complex problems. A lot of people are researching algorithms and usage cases for computers or AI machines that could potentially outperform classical computers. Here, were developing the hardware that could enable quantum computers to implement these algorithms. This shows the power of universities seeding these ideas that eventually make their way to industry and are integrated into practical machines.

Graphene and Quantum Computing: A Match Made in Heaven

Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, has been hailed as a wonder material since its discovery in 2004. This ultra-thin, ultra-strong material has the potential to revolutionize industries ranging from electronics to medicine. One area where graphenes unique properties could have a particularly profound impact is in the realm of quantum computing.

Quantum computing is an emerging field that seeks to harness the strange and powerful properties of quantum mechanics to perform calculations far beyond the capabilities of classical computers. While still in its infancy, quantum computing has the potential to revolutionize fields such as cryptography, drug discovery, and artificial intelligence. However, the development of practical quantum computers has been hampered by a number of technical challenges, including the need for materials that can support and manipulate delicate quantum states.

This is where graphene comes in. Graphenes remarkable electronic properties make it an ideal candidate for use in quantum computing. For one, graphene is an excellent conductor of electricity, with electrons able to move through the material with very little resistance. This property could be used to create ultra-fast, low-power quantum computing devices.

Moreover, graphenes two-dimensional structure gives it unique quantum properties. Electrons in graphene behave as if they have no mass, allowing them to move at extremely high speeds and follow the rules of quantum mechanics rather than classical physics. This means that graphene could potentially be used to create quantum bits, or qubits, the fundamental building blocks of quantum computers.

Qubits are the quantum equivalent of classical bits, which represent information as either a 0 or a 1. However, qubits can exist in a superposition of both 0 and 1 simultaneously, allowing quantum computers to perform many calculations at once. This parallelism is what gives quantum computers their immense potential for solving complex problems.

One of the key challenges in building a quantum computer is maintaining the delicate quantum states of qubits. Quantum states are easily disturbed by their environment, leading to errors in calculations. This phenomenon, known as decoherence, is a major obstacle to the development of practical quantum computers.

Graphenes unique properties could help address this issue. The materials two-dimensional structure means that it can be easily integrated with other materials, such as superconductors, which are essential for maintaining quantum states. Additionally, graphenes high electron mobility could be used to create devices that can manipulate and control qubits with high precision.

Recent research has demonstrated the potential of graphene for quantum computing applications. In one study, scientists at the Massachusetts Institute of Technology (MIT) were able to create a graphene-based device that could control the flow of electrons with a high degree of precision. This device, known as a valleytronics system, could potentially be used to create qubits that are less susceptible to decoherence.

In another study, researchers at the University of Cambridge were able to use graphene to create a new type of qubit that is both more stable and more easily controlled than existing designs. This topological qubit could be a major step forward in the development of practical quantum computers.

While there is still much work to be done, it is clear that graphene has the potential to play a crucial role in the development of quantum computing. The marriage of these two cutting-edge fields could lead to breakthroughs that were once thought to be the stuff of science fiction. As researchers continue to explore the potential of graphene and quantum computing, we may be on the cusp of a new era of technological innovation that will reshape our world in ways we can only begin to imagine.

The artificial intelligence craze sweeping the planet has not skipped intelligence and defense systems, especially since the Israel Defense Forces and many other western militaries have been utilizing it for years - but it's the leap in generative AI that is noteworthy.

How quickly has every child been able to transform himself into a professional painter, author and even hacker, is a phenomenon that we all need to take a pause for and be mindful of, as it exemplifies how quickly forceful technology has made the shift from obscure laboratories, hidden from public view, to the every child's bedroom.

The IDF is spearheading cyberwarfare

Take quantum computing, for instance.

The crumbling of cipher keys has become every security system's biggest nightmare scenario for 2023. We're talking about a situation in which internal communications, computer networks and operational documents become publicly exposed, which will surely signal an unprecedented security breach.

As far as Israel goes, it was in 1997, when the Ansariya ambush, in which a unit from the Israeli Navys special operation unit, Shayetet 13, on a mission in South Lebanon, stumbled into a deadly ambush by Islamic Resistance guerrillas, leaving 12 operatives dead.

While in a civilian context the day-to-day war of attrition against hackers is conducted in the name of protecting private clients and patents, in the military realm, it is about protecting a country's strategic assets.

In a more narrowly defined Israeli context, it means protecting the Iron Dome missile defense system, the digital emergency alarm array and operational details ingrained in top secret IDF plans.

Cyberwarfare is divided between military intelligence and C4I corps, the IDF's elite technological unit. The Cyber Defense Brigade was established six years ago, and the most intriguing component of that brigade is the Center of Encryption and Information Security.

That's where ciphers and codes are developed, serving the IDF, Shin Bet, Mossad and many other governmental bodies.

The Center of Encryption and Information Security officials say that the most convenient part of cyber is dealing with what's known and familiar. The future, on the other hand, gets trickier to deal with, and that entails quantum computing.

It is a rather advanced processing method, based on observations made in quantum mechanics. "Quantum computers will be able to instantaneously perform tasks that today's computers would require at least a millennia. They would easily crack today's ciphers," a lieutenant colonel from the unit says.

"When you currently connect to your bank account, work, email or WhatsApp, various components ensure the security of your access. One crucial element is an algorithm called RSA, which relies on intricate mathematical problems," he says.

"While these problems can theoretically be solved, they are notoriously complex and time-consuming, even for supercomputers. However, with the advent of quantum computers, RSA encryption could be defeated within seconds.

"This implies that hackers or adversaries would possess nearly limitless computing power to decrypt traditional ciphers. Consequently, sensitive and encrypted data could be compromised today, with the potential to decrypt it once a quantum computer of sufficient strength becomes accessible," the lieutenant colonel explains.

Could this danger materialize tomorrow? "That would depend on your definition of tomorrow. Major technology companies are already demonstrating remarkable advancements in this domain, with estimates suggesting that they will develop a stable and dependable quantum computer within the next five to 10 years.

"From the perspective of the IDF, this timeline is alarmingly brief. We consider it highly likely that within the coming decade, quantum computers will fall into the hands of entities interested in accessing the IDF's classified information. Consequently, we have been diligently studying this subject since the mid-2000s."

"Keep in mind, this is uncharted territory," says a major in the unit. "Here, we do not rely on pre-existing textbooks or established foundations. We are tasked with starting from scratch, immersing ourselves in comprehensive self-learning and research. What's more, we take on the responsibility of developing our own curriculum and training individuals from the ground up."

Aside from its computational applications, quantum technology has the kind of applications that could rival an episode of "Star Trek." Many of these advancements are poised to have a profound impact on the military system, with some already being partially realized.

An example of this can be observed in the use of Lidar technology, which employs quantum sensors for laser-based object mapping. It is already integrated into autonomous vehicles, smartphones and is instrumental in generating highly detailed maps.

Quantum sensors will also enable remarkably precise navigation, independent of GPS satellites or similar systems. Furthermore, quantum communication promises stable and secure connections over considerable distances, often spanning dozens of miles.

But with many of those serving in these specialized cyber units ranging from 18 to 30 years of age, it raises the question: How would a bunch of kids solve problems that the planet's finest minds are still struggling with?

The lieutenant colonel is optimistic about that. "First, and this may sound trite, I firmly believe in the exceptionalism of the 'Jewish mind,' particularly in the realm of mathematics. Since its inception, the proportion of graduates from the mathematical field who have gone on to become esteemed doctors and professors in academia is remarkable.

"Second, the IDF possesses a unique advantage in its ability to bring together the brightest minds in one place, all working toward solving the same problems. Unlike academia, where minds are dispersed and lack a unified mission, the IDF provides a concrete operational context for our missions.

"Moreover, we receive continuous support from reserve personnel and external consultants who have successfully passed through rigorous security clearance protocols. The IDF benefits from a wealth of research knowledge accumulated over decades."

How do you research quantum computing with a quantum computer? "The research we conduct is based on algorithms and, in theory, it can be performed since we understand the behavior involved. However, it's evident that for demonstration and testing purposes, a quantum computer is necessary, which is currently unavailable in Israel.

"To overcome this limitation, we rely on quantum computing services provided by prominent international software giants through the cloud. We make use of these services extensively for our research endeavors."
