Realizing highly accurate quantum error correction even for quantum computers with about 10,000 physical qubitsOsaka University, Fujitsu LimitedNews Facts:

Tokyo and Osaka, March 23, 2023

Fujitsu and Osaka Universitys Center for Quantum Information and Quantum Biology (QIQB) today revealed the development of a new, highly efficient analog rotation quantum computing architecture, representing a significant milestone toward the realization of practical quantum computing. The new architecture reduces the number of physical qubits required for quantum error correction a prerequisite for the realization of fault-tolerant quantum computing by 90% from 1 million to 10,000 qubits. This breakthrough will allow research to embark on the construction of a quantum computer with 10,000 physical qubits and 64 logical qubits (4), which corresponds to computing performance of approximately 100,000 times that of the peak performance of conventional high performance computers.

Moving forward, Fujitsu and Osaka University will further refine this new architecture to lead the development of quantum computers in the early FTQC era, with the aim of applying quantum computing applications to a wide range of practical societal issues including material development and finance.

Gate-based quantum computers are expected to revolutionize research in a wide range of fields including quantum chemistry and complex financial systems, as they will offer significantly higher calculation performance than current classical computers.Logical qubits, which consist of multiple physical qubits, play a major key role in quantum error correction technology, and ultimately the realization of practical quantum computers that can provide fault-tolerant results.

Within conventional quantum computing architectures, calculations are performed using a combination of four error-corrected universal quantum gates (5) (CNOT, H, S, and T gate). Within these architectures, especially quantum error correction for T-gates requires a large number of physical qubits, and rotation of the state vector in the quantum calculation requires repeated logical T-gate operations for approximately fifty times on average. Thus, the realization of a genuine fault-tolerant quantum computer is estimated to require more than one million physical qubits in total.

For this reason, quantum computers in the early FTQC era using conventional architecture for quantum error correction can only conduct calculations on a very limited scale below that of classical computers, as they work with a maximum of about 10,000 physical qubits, a number far below that required for genuine, fault-tolerant quantum computing.

To address these issues, Fujitsu and Osaka University developed a new, highly efficient analog rotation quantum computing architecture that is able to significantly reduce the number of physical qubits required for quantum error correction, and enable even quantum computers with 10,000 physical qubits to perform better than current classical computers, accelerating progress toward the realization of genuine, fault-tolerant quantum computing.

Fujitsu and Osaka University have been promoting joint R&D in quantum error correction technology including new quantum computation architectures for the early FTQC era at the Fujitsu Quantum Computing Joint Research Division, a collaborative research effort of the QIQB, established on October 1, 2021 at the campus of Osaka University as part of Fujitsus Fujitsu Small Research Laboratory program (6).

By redefining the universal quantum gate set, Fujitsu and Osaka University succeeded in implementing a phase rotating gate a world first which enables highly efficient phase rotation, a process which previously required a high number of physical qubits and quantum gate operations.

In contrast to conventional architectures that required repeated logical T-gate operations using a large number of physical qubits, gate operation within the new architecture is performed by phase rotating directly to any specified angle.

In this way, the two parties succeeded in reducing the number of qubits required for quantum error correction to around 10% of existing technologies, and the number of gate operations required for arbitrary rotation to approx. 5% of conventional architectures. In addition, Fujitsu and Osaka University suppressed quantum error probability in physical qubits to about 13%, thus achieving highly accurate calculations.

The newly developed computing architecture lays the foundation for the construction of a quantum computer with 10,000 physical qubits and 64 logical qubits, which corresponds to computing performance of approximately 100,000 times that of the peak performance of conventional high performance computers.

Research and development of the new quantum computing architecture was supported by the following programs: Japan Science and Technology Agency (JST), The program on open innovation platform for industry-academia co-creation (COI-NEXT), "Quantum Software Research Hub" (JPMJPF2014); JST Moonshot Goal 6 "Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050", R&D project "Research and Development of Theory and Software for Fault-tolerant Quantum Computers" (JPMJMS2061); MEXT Quantum Leap Flagship Program (MEXT Q-LEAP) "Development of quantum software by intelligent quantum system design and its applications" (JPMXS0120319794) and "Development of quantum software applications by fast classical simulator of quantum computers" (JPMXS0118067394).

For the first time, scientists have been able to identify and manipulate photons particles of light which are interacting with each other.

The breakthrough has implications for quantum technologies including advances in medical imaging and quantum computing.

Photons can also be thought of as packets of light energy, or quanta of light. Over a century ago, physicists coming to grips with the weird world of quantum mechanics discovered wave-particle duality. Photons, electrons and other subatomic particles behaved not as either particles or waves, but exhibited characteristics of both forms.

Einstein first proposed in 1916 (published in 1917) that you could get atoms to emit photons by exciting the electrons in the atoms with energy. This type of photon scattering is seen every day now in lasers (LASER = Light Amplification by Stimulated Emission of Radiation) with large numbers of photons.

But this new research shows stimulated emission for single photons.

Now, scientists at the University of Sydney and Switzerlands University of Basel teamed up to observe stimulated emission for single photons for the first time.

The physicists were able to directly measure the time delay between one photon and a pair of photons scattering of a single quantum dot.

A quantum dot is a type of artificial atom produced using a nanometre-sized crystal structure. Quantum dots can convert light of one wavelength into another wavelength photon.

This opens the door to the manipulation of what we can call quantum light, says the University of Sydneys DrSahand Mahmoodian. This fundamental science opens the pathway for advances in quantum-enhanced measurement techniques and photonic quantum computing.

Understanding the nature of light not only captures the imagination, but underpins much of modern technology including mobile phones, global communications networks, computers, GPS and modern medical imaging.

Further advances in our knowledge of how light works promises to underpin new technological innovations.

Light has already shown promise, through optical fibres, as a replacement for electrical networks for near distortion-free and ultra-fast transfer of information.

Its when we want light to interact that things get a little messy.

For example, interferometers are now common measuring tools that work by merging two or more light sources to create an interference pattern. Interferometers are used in medical imaging and in some of the most advanced experiments in the world such as LIGO at Caltech which was the first to detect gravitational waves in 2015.

Interferometers are limited in their sensitivity by quantum effects which make it difficult to tell the many photons in the device apart.

The device we built induced such strong interactions between photons that we were able to observe the difference between one photon interacting with it compared to two, says Dr Natasha Tomm from the University of Basel. We observed that one photon was delayed by a longer time compared to two photons. With this really strong photon-photon interaction, the two photons become entangled in the form of what is called a two-photon bound state.

Such quantum light devices, as opposed to interferometers which until now have used classical laser light, promise to have far higher resolution and sensitivity.

The researchers say this will be useful in fields such as medical imaging, and further research will be aimed at manipulating quantum light to produce fault-tolerant quantum computers.

This experiment is beautiful, not only because it validates a fundamental effect stimulated emission at its ultimate limit, but it also represents a huge technological step towards advanced applications, Tomm explains.

We can apply the same principles to develop more-efficient devices that give us photon bound states. This is very promising for applications in a wide range of areas: from biology to advanced manufacturing and quantum information processing.

The research is published in Nature Physics.

At the start of March, the venture capital arms of two blue chip defense hardware companies revealed a pair of investments in startup technology companies as part of the constant search for "what's next."

Roughly two weeks on from that, the venture organizations of Lockheed Martin and Raytheon Technologies have a new pair of investments in emerging firms to talk about.

Here are their latest finds announced Wednesday.

Lockheed Martin Ventures

For this team of the world's largest defense company, identifying creations of promise in power and propulsion is a top priority as they look to bring those technologies into the military environment.

REGENT, a maker of electric-powered sea vehicles, represents the newest investment of Lockheed Martin Ventures and follows on from the backing of electric motor manufacturer H3X Technologies announced at the beginning of March. Terms of the investment in REGENTwhich stands forRegional Electric Ground Effect Nautical Transportwere not disclosed.

As REGENT and Lockheed see things: The Defense Department wants to incorporate high-speed, low-cost, low-signature, runway-independent mobility into maritime vehicles. REGENT designs its seagliders to travel at airplane-like speeds for up to 180 miles between destinations on all-electric, zero-emission power.

The company was founded in late 2020 and touts having secured $7.9 billion in orders since then from major airlines and leading ferry operators. REGENT plans to use Lockheed's investment for adapting the seagliders for use in defense missions such as logistics resupply, cargo transport, and search and rescue.

We believe that REGENT seagliders can bring tailored solutions to the future battlespace," Chris Moran, vice president and general manager of Lockheed Martin Ventures, said in a release. This investment reflects our commitment to innovating technologies that have the potential to transform the way we adapt to our customers needs and support mission success."

"We see defense strategy evolving toward an island-hopping force featuring agile, affordable, and distributed craft, REGENT's co-founder and chief executive Billy Thalheimer added. This investment is a strong signal that seagliders can fill this immediate need in the high-priority missions faced by our Department of Defense."

RTX Ventures

This division of Raytheon Technologies is one of several investors that are committing capital to Strangeworks, a five-year-old company focused on making quantum computing a reality.

Strangeworks fetched $24 million in a Series A funding led by Hitachi's venture capital arm, with RTX Ventures and IBM lined up as new investors. Lightspeed Venture Partners, Great Point Ventures and Ecliptic Capital made follow-on investments into a company they helped stand up with initial seed money.

The idea behind quantum is to increase computing power by encoding information through chains of entangled subatomic particles.

Traditional computers encode information through bits that are represented as either a 1 or 0. But quantum bits, or qubits, work to superimpose that bit value to be both a 1 and 0 at the same time and thus generating more computing power.

Strangeworks secured this funding round for its five-year plan to further develop the quantum computing capability and incorporate artificial intelligence into those new products.

"We believe Strangeworks' platform and their ability to make quantum and high-performance computing more accessible can support a wide range of applications in the aerospace, defense, and commercial sectors," Dan Ateya, president and managing director of RTX Ventures, said in a release.

"Raising the Series A from these exceptional investors in this challenging economic climate sends a clear message to the market on where enterprise companies are placing their bets in the race to create quantum value," Strangeworks' founder and CEO William Hurley added.
