After researching: Quantinuum and D-Wave complain about leadership role in the quantum area

• D-WAVE claims quantum supervision for material simulation
• Quantinuum creates mathematically proven “real randomness”
• Research discussed critically among scientists

The quantum computer industry is currently experiencing rapid progress. While classic computers are reaching physical limits, quantum computers promise exponential performance increases for certain calculations. Industry sizes such as Nvidia boss Jensen Huang have already admitted that useful quantum computers may be a reality much earlier than assumed. Now the quantum computer companies D-Wave Quantum and Quantinuum have announced new breakthroughs that further underpin the potential of the technology-but not without criticism and open questions.

D-Wave Quantum announces “quantum supervision”

D-Wave Quantum announced in mid-March by press release that her annealing quantum computer had carried out a complex material simulation within minutes, while the supercomputer Frontier, which is considered one of the fastest in the world, would need around one million years for this. The simulation affected the properties of complex magnetic materials that are used in technologies such as smartphones or medical devices and are relevant for material research. A corresponding research paper from D-Wave was published in the specialist magazine “Science”.

“Our success undoubtedly shows that D-Wave’s annealing quantum computers are now able to solve useful problems that are outside the range of the most powerful supercomputers in the world,” Dr. Alan Baratz, CEO of D-Wave, quoted in the press release. He further said that “the demonstration of the superiority of the quantum calculation in a useful problem” has so far been unique in the entire industry and worldwide. For customers of D-Wave Quantum, there would now be a “tangible added value through annealing quantum computers”, says Baratz.

D-Wave scientist Andrew King also spoke in view of the breakthrough of “quantum supervision”. This means the ability to solve a problem with a quantum computer that is impossible for a conventional computer. “We solve an important problem in an area that is completely unsolvable for classic methods. That is why we call it quantum supervision,” said King to the “Wall Street Journal”.

However, there is a lot of criticism of this choice of words. According to the “Wall Street Journal”, Google already announced in 2019 that quantum supervision was achieved, and the expert side notes that D-Wave should speak better of “quantum advantage” or “quantum benefit” instead of “quantum superiority”. Because the paper from D-Wave is based on research work last year and does not take into account modern computer technology, said Miles Stoudenmire, a researcher at the Center for Computational Quantum Physics of the Flatiron Institute. According to the current status, optimal classic algorithms could significantly reduce the temporal gap and the calculations can also be carried out on conventional computers using tensor network.

Quantinuum reaches milestone with certified quantum dusk

But in addition to D-Wave Quantum, the Honeywell subsidiary Quantinuum recently made progress in the area of ​​quantum computers and, according to its own statements, has thus consolidated “its leadership position in the fast-developing quantum computer industry”. According to the press release from the end of March, Quantinuum made a breakthrough in the production of certified quantum accessibility with the help of a commercial quantum computer. With the 56-qubit system H2-1, it was successful to generate real random numbers-according to “Barron’s” also called “certified randomness”, which are of great importance for cryptographic applications. The results would show the first implementation of a certified random expansion protocol, which creates more randomness than it could not be used and cannot be achieved with classic methods, says Quantinuum. Here, too, the Frontier supercomputer was used as a comparison and the research results in a specialist magazine, this time “Nature”, were published.

As “Barron’s” writes, Quantinuum could enter the list of companies thanks to the latest development that claims to have proven to have proven quantum supervision. The concept of “quantum supervision” also falls in the press release of Quantinuum, but only with reference to the notification of Google from 2019. The company does not seem to claim this name for itself. However, the company is very self-confident: “By using the powerful properties of quantum mechanics, we have shown how to generate the random numbers that are decisive for safe electronic communication. We have created a practical application that was unreachable before the reliability of the H2 quantum computer due to its accuracy and scalability,” says the press release. The Honeywell subsidiary, which could possibly be brought to the stock exchange in the future, is also certain that “the time, in quantum computing, was removed from social and economic effects in quantum computing, [..] Gone “is and describes its breakthrough as” first commercial application for quantum computers “, which is so reliable that it becomes possible to make it a commercial product.

However, scientists also have concerns about the practical applicability of this technology. Quantinuum’s performance is impressive if you demonstrate the quantum supervision with captured ions, but it is not yet good enough for cryptographic applications with high missions, said Scott Anderson, director of the Quantum Information Center at the University of Texas in Austin, according to “Barron’s”. As the news portal writes with a view to the specialist articles published in “Nature”, the study authors would appeal to the restrictions and only speak of “a step towards the practical applicability of modern quantum computers”. However, according to them, the results are not yet commercially applicable – which means that they position themselves significantly more reserved than Quantinuum itself.

Commercial perspectives continue to be uncertain

Despite the progress made by D -Wave Quantum and Quantinuum, the question of the commercial applicability of quantum technology remains open – and also the question of who actually has quantum superiority and the leadership role in the industry, which currently seem to complain to themselves in view of their latest breakthroughs, can rightly claim.
