Last November, IBM launched its 127-qubit Eagle, surpassing Chinas 113-qubit Jiuzhang to become the worlds fastest quantum computer. Now, China risks falling further behind in the quantum computing race as the United States reportedly weighs new export controls on the game-changing technology.

The new ban, if implemented, would target quantum computing, artificial intelligence software and other emerging technologies that could have security implications vis-a-vis China. The ban would mark a next salvo on the Biden administrations October 7 move to block high-end chips and advanced chip-making equipment exports to China.

Bloomberg reported that US industry experts are now weighing in on the potential parameters of the restrictions, which are still preliminary, and that US allies are being consulted. Analysts say any such ban would further antagonize China, which strongly protested the October 7 bans, and could put the two rivals on a dangerous collision course.

Chinese media commentators say the US aims to strengthen efforts to slow Chinas development in emerging technologies, where the two strategic rivals are racing to lead the way. The commentators suspect the US will not only aim to block China from obtaining key quantum computing parts and software but also force other countries to uphold the bans.

The US is making no secret of how it views the emerging and sensitive technology.

US National Security Advisor Jake Sullivan said ina speech last monthon technology, competitiveness and national security that computing-related technologies, including microelectronics, quantum information systems and artificial intelligence as among developments set to play an outsized importance over the coming decade. He also noted the importance of export controls to maintain as large of a lead as possible over rivals.

Currently, Alphabets Google, Intel, Microsoft and IBM are all investing heavily in quantum computing projects. Other major players in the sector include US-based IonQ and Japans Fujitsu Ltd.

Quantum computers mark, well, a quantum leap over the speed and power of current supercomputers.

That means they will likely be able to crack and bypass the encryption technologies used to secure current computer communications. More broadly, the technology is expected to unleash waves of new innovation that will revolutionize industry, communications and, crucially, defense.

On September 15, US President Joe Biden signed an executive order urging the US Treasury DepartmentsCommittee on Foreign Investment into the US (CFIUS) to ensure more robust consideration of evolving national security risks.

What may otherwise appear to be an economic transaction undertaken for commercial purposes may actually present an unacceptable risk to US national security when conducted with foreign adversaries or countries of special concern, according to the Executive Order.

It said the committee should consider the transactions effect on US supply chain resilience and national security across the microelectronics, AI, biotechnology and quantum computing sectors.

The Biden administration is now working on an outbound investment review mechanism that would scrutinize money heading to certain Chinese technologies, and new quantum computing and artificial intelligence controls could be included, according to an anonymous source quoted by Bloomberg.

Biden has said the new curbs unveiled by the US Commerce Departments Bureau of Industry and Security (BIS) on October 7 have already successfully blocked Chinas access to key US chip technologies. Thecurbshave also limited how US citizens and residents are allowed to work and collaborate with Chinese tech firms.

Secrss.com, a Shanghai-based research institute, noted in several articles this year that quantum computing can be applied in computing, communication, navigation, power and military defense industries. It said quantum computing had the potential to change the results of future wars.

One article said quantum computers can be used to initiate cyber warfare by decoding passwords and bypassing encryption used on current digital computers. It said quantum computing technologies can also be used to navigate drones and submarines.

Another article, citing a report in the European Physical Journal, said a quantum radar would be launched one day and used in space war.

China is making strong progress in the field in the current open trading environment. The 66-qubit Zuchongzhi 2, for instance, is reportedly 10 million times faster than Googles 55-qubit Sycamore.

In December 2020, a University of Science and Technology of China research team led by scientist Pan Jianwei launched Jiuzhang, a light-based or photonics quantum computer that can work at room temperature. It is said to be 10 billion times faster than Googles Sycamore.

In May 2021, Pan and his team launched Zuchongzhi 2, a superconducting quantum computer that needs to work at a temperature close to absolute zero. Jiuzhang and Zuchongzhi 2s details were published last November by the Physical Review Letters, a scientific journal of the American Physical Society.

Soon thereafter, IBMs Eagle surpassed Zuchongzhi 2 to become the worlds fastest superconducting quantum machine, underscoring the two sides budding rivalry in the filed.

Researchers have demonstrated that large numbers of quantum bits, or qubits, can be tuned to interact with each other while maintaining coherence for an unprecedentedly long time, in a programmable, solid-state superconducting processor.

Long-Lived Coherent Quantum States in a Superconducting Device for Quantum Information Technology

Scientists have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, can be tuned to interact with each other while maintaining coherence for an unprecedentedly long time, in a programmable, solid-state superconducting processor. This breakthrough was made by researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom.

Previously, this was only possible in Rydberg atom systems.

A qubit, or quantum bit, is a basic unit of quantum information. It is essentially the quantum version of conventional computers most basic form of information, the bit.

In a new paper, scientists demonstrated a first look at the emergence of quantum many-body scarring (QMBS) states as a robust mechanism for maintaining coherence among interacting qubits. Such exotic quantum states offer the appealing possibility of realizing extensive multipartite entanglement for a variety of applications in quantum information science and technology to achieve high processing speed and low power consumption. The paper, which will be published today (October 13) in the journal Nature Physics, is authored by ASU Regents Professor Ying-Cheng Lai, his former ASU doctoral student Lei Ying and experimentalist Haohua Wang, both professors at Zhejiang University in China.

QMBS states possess the intrinsic and generic capability of multipartite entanglement, making them extremely appealing to applications such as quantum sensing and metrology, explained Ying.

Classical, or binary computing relies on transistors which can represent only the 1 or the 0 at a single time. In quantum computing, qubits can represent both 0 and 1 simultaneously, which can exponentially accelerate certain computing processes.

In quantum information science and technology, it is often necessary to assemble a large number of fundamental information-processing units qubits together, explained Lai. For applications such as quantum computing, maintaining a high degree of coherence or quantum entanglement among the qubits is essential.

However, the inevitable interactions among the qubits and environmental noise can ruin the coherence in a very short time within about ten nanoseconds. This is because many interacting qubits constitute a many-body system, said Lai.

Key to the research is insight into delaying thermalization to maintain coherence, considered a critical research goal in quantum computing.

From basic physics, we know that in a system of many interacting particles, for example, molecules in a closed volume, the process of thermalization will arise. The scrambling among many qubits will invariably result in quantum thermalization the process described by the so-called Eigenstate Thermalization Hypothesis, which will destroy the coherence among the qubits, said Lai.

These findings will help move quantum computing forward and will have applications in cryptology, secure communications, and cybersecurity, among other technologies, says Lai.

Quantum computing can soon address many of the worlds toughest, most urgent problems.

Thats why the semiconductor legislation Congress just passed is part of a $280 billion package that will, among other things, direct federal research dollars toward quantum computing.

Quantum computing will soon be able to:

The economy and the environment are clearly two top federal government agenda items.Congress in July was poised to pass the most ambitious climate bill in U.S. history. The New York Times said that the bill would pump hundreds of billions of dollars into low-carbon energy technologies like wind turbines, solar panels and electric vehicles and would put the United States on track to slash its greenhouse gas emissions to roughly 40% below 2005 levels by 2030. This could help to further advance and accelerate the adoption of quantum computing.

Because quantum technology can solve many previously unsolvable problems, a long list of the worlds leading businesses including BMW and Volkswagen, FedEx, Mastercard and Wells Fargo, and Merck and Roche are making significant quantum investments. These businesses understand that transformation via quantum computing, which is quickly advancing with breakthrough technologies, is coming soon. They want to be ready when that happens.

Its wise for businesses to invest in quantum computing because the risk is low and the payoff is going to be huge. As BCG notes: No one can afford to sit on the sidelines as this transformative technology accelerates toward several critical milestones.

The reality is that quantum computing is coming, and its likely not going to be a standalone technology. It will be tied to the rest of the IT infrastructure supercomputers, CPUs and GPUs.

This is why companies like Hewlett Packard Enterprise are thinking about how to integrate quantum computing into the fabric of the IT infrastructure. Its also why Terra Quantum AG is building hybrid data centers that combine the power of quantum and classical computing.

Amid these changes, employees should start now to get prepared. There is going to be a tidal wave of need for both quantum Ph.D.s and for other talent such as skilled quantum software developers to contribute to quantum efforts.

Earning a doctorate in a field relevant to quantum computing requires a multi-year commitment. But obtaining valuable quantum computing skills doesnt require a developer to go back to college, take out a student loan or spend years studying.

With modern tools that abstract the complexity of quantum software and circuit creation, developers no longer require Ph.D.-level knowledge to contribute to the quantum revolution, enabling a more diverse workforce to help businesses achieve quantum advantage. Just look at the winners in the coding competition that my company staged. Some of these winners were recent high school graduates, and they delivered highly innovative solutions.

Leading the software stack, quantum algorithm design platforms allow developers to design sophisticated quantum circuits that could not be created otherwise. Rather than defining tedious low-level gate connections, this approach uses high-level functional models and automatically searches millions of circuit configurations to find an implementation that fits resource considerations, designer-supplied constraints and the target hardware platform. New tools like Nvidias QODA also empower developers by making quantum programming similar to how classical programming is done.

Developers will want to familiarize themselves with quantum computing, whichwill be an integral arrow in their metaphorical quiver of engineering skills. People who add quantum skills to their classical programming and data center skills will position themselves to make more money and be more appealing to employers in the long term.

Many companies and countries are experimenting with and adopting quantum computing. They understand that quantum computing is evolving rapidly and is the way of the future.

Whether you are a business leader or a developer, its important to understand that quantum computing is moving forward. The train is leaving the station will you be on board?
