Scientists have used artificial intelligence to discover an easier way to form a quantum tangle between atomic molecules, which paves the way for the simplest quantum techniques.

When molecules such as photons become intertwined, they can share quantum properties – including information – regardless of the distance between them. This phenomenon is important in Quantum physics It is one of the features that are made Quantum computers Very strong.

But links Quantum It has usually demonstrated the challenge of scientists to form it. This is because it requires preparing a separate interlocking couple, then measuring the strength of the tangle-it is called the bell-to-let’s measurement of both husbands.

These measurements cause the quantum system to break down and leave the non -measured photons, although they do not interact directly with each other. This “tangle replacement” process can be used in quantum transfer.

In a new study, published on December 2, 2024 in the magazine Physical review messagesScientists use PytheusAI tool created specifically for the design of quantum visual experiments. The authors of the paper initially began to reproduce fixed protocols to exchange tangles in quantum communications. However, the artificial intelligence tool continued to produce a much simpler method to achieve quantum tangles for photons.

“The authors were able to train a nervous network on a set of complex data that describes how you prepared this type of experience in many different circumstances, and the network has already learned physics behind,” Sofia ValekorssaPhysical research for quantum technology initiative in SerenWho did not participate in the new research, tell Live Science.

Take advantage of artificial intelligence to simplify quantum tangles

The artificial intelligence tool suggested to stand out because the tracks of the tracks Photons It could not be distinguished: When there are many potential sources from which photons can come from, and if their origins become cannot be distinguished from each other, the tangle can be produced between them when there is nothing before.

Although scientists were initially skeptical of the results, the tool continued to return the same solution, so they tested the theory. By controlling the sources of photon and ensuring that they are not distinguished, physicists have established conditions where photons detection discovered in certain paths that two others appeared tangles.

This penetration in quantum physics simplified the process through which quantum tangle can be formed. In the future, it can have effects on quantum networks used in safe messaging, making these technologies more feasible.

“The more we can rely on simple technology, the more we can increase the scope of applications,” said Valekorssa. “The possibility of building more complex networks can be branching in various engineering a significant impact on the individual state of the end.”

Whether it is practical to expand technology in a commercially viable process, however, environmental noise and device defects may cause instability in the quantum system.

The new study also presented a convincing argument for the use of artificial intelligence as a research tool by physicists. “We are more looking to provide artificial intelligence, but there are still little doubts, mostly due to the physical role as soon as we start going this way,” said Valekorssa. “It is an opportunity to get a very interesting result and shows in a very convincing way how this can be a tool that physicists use.”
