The researchers claim the first “unconditional evidence” of the quantum feature. What happens after that?

The quantum computers are already here, although they are not easily clear. Now, the researchers say ADVANTUM Advantage-a field teacher who has long been presented by classic computers superior to the superior performance-appears at the end. But the story comes with an important warning.

Research conducted by scientists at the University of Texas at Austin and Colorado Computing and the implementation of a “unconditional” feature, which is sometimes referred to as quantitative excellence. As the researchers formulated, “their result can be proven and permanent: the future development in the classic algorithms cannot bridge this gap.” Preparation, which has not been reviewed from the peer yet Arxiv Earlier this month.

Gizmodo communicates with many experts in this field, who have confirmed the new results. They added that the experiment, although it is worthy of praise, is not the most practical use of a quantum computer – which already gets a useless user.

Then again, the “quantum feature” is a strange concept, amazingly flexible with many possible applications. In general, the results are definitely worth a closer look.

Alice and Bob make a veil

Quantum lovers may be familiar with Alice and Bob, two fictional people Often summons For quantitative thought experiences. In the context of the new experience, Alice and Bob are researchers cooperating at an expense using one device. They receive different inputs at different points in time, but only cann’t it just send a bob message, not the other way around. Based on Alice’s message, Bob must decide how to measure and explain the production of a final output.

According to the paper, “the use of the quantum message can reduce the amount of contacts required in the captive factor compared to any protocol that uses classic connection alone.” In other words, a small quantity message can replace a much larger classic message. To prove their point of view, the team repeated the experience 10,000 times on the quantum computers of the H1-1 from the Quantinuum, along with the careful sporty checking of their protocol.

Surprisingly, they found that the quantum computer only needs 12 Qubits (Qubits is the smallest unit of information for quantum computers) to solve this problem. In contrast, even the most efficient classic computers need 330 bits.

A different way to play the game

“This is a completely different type of quantum feature than we have seen before – not better or worse, but it proves something completely different from previous experiences,” Bill VivmanTell the computer world at the University of Chicago, Gizmodo in an email. Fefferman had previously cooperated with Senior authors Scott Aronson, but he did not participate in the new study.

Fefferman explained that scientists usually equate the quantum feature to “seek to make an account on a quantum computer that can be solved significantly faster than any classic computer.” On the contrary, the new experience “excels quantum information” achieves, as the focus on speed is not as much as it is to use a fewer of Qubits to solve the problem that classic computers need a lot of bits.

“It is true that its results are not conditional, meaning that they do not depend on unproven assumptions.” “This, of course, is a great advantage for this new experience, but it also inherited by” transferring goals of goals. “

Gizmodo called the authors of the study, who said they could not comment until the paper is officially published.

Click on the feature

The results raise questions about the broader goals to prove the quantum feature. The IBM Quantum Gizmodo Director also told A. Previous interviewThe possible answer is to ask how quantum computers can enhance the computing problems that we already know.

But as Fefferman indicated, there is not necessarily a better or worse approach to reaching the quantum advantage – although this “goal” seems to be the sacred cup for the struggle of the field to prove its value.

This may be a product of the history of quantum computing, Giuseppe CarleleI explained my EPFL account in Switzerland, which did not participate in the new work, for Gizmodo in a video call. The rapid growth of quantum computing makes it easy to forget the extent to which the appropriate devices are available for a theoretical test.

“So, the field has historically developed in the past twenty years or 30 years of mathematics, instead of the applied field where, if you want, you can use a machine to run things,” said Carlele, who spoke with Gizmodo about the history of quantum computing. As a result, most of the analysis in the field remained in theoretical levels longer than scientists hoped.

But as devices are advanced and rapidly developed, this trend gradually turns-as it should, as it should. He said that more projects are far from designing quantum features “specifically designed to show a feature”, and it instead turns into places where computers can help quantum, not necessarily.

This is actually closer to the “origins” of the field. Richard Fainman, the physicist scientist at the foundations of quantum computing, Proposal Quantum computers should predict quantum phenomena. Certainly, there may not be much of the “associated money”, but it is “tremendous importance to theoretical physics”, especially with regard to the basic questions about our world.

Anything does not make it easy

The new experience may be combined to prove its immediate relationship with practical application. But somehow, Preprint is committed to Feynman’s advice. It is definitely a theoretically strong view of the use of quantum devices to investigate quantum concepts.

At this particular moment, it makes it look separate from reality. Then again, when did anything give easy answers? However, if the history of science is any evidence, then the best discoveries come from the most unprecedented unexpected endeavors. We will just have to monitor.
