Scientists have used AI to find an easy method of forming quantum tangling between subatomic particles, making the way to more quantum technologies.
When particles such as photons are tangled, they can share quantum properties – including information – regardless of the distance between them. This phenomenon is important in Quantum physics and is one of the characteristics they make Quantum computers So powerful.
But quantum tangles are usually challenging for the formation of scientists. This is because it requires the preparation of two separate tangled pairs, and then measures the force of tangled-a detached measurement of the bell-on photon by each of the couples.
These measurements cause the quantum system to collapse and leave the two non -interconnected photons entangled, although they have never interacted directly with each other. This “braid” process can be used for quantum teleportation.
In a new study published on December 2, 2024 in the magazine Letters of physical examinationscientists DrinkingAI tool that was specifically designed for designing quantum-optic experiments. The authors of the document initially determine to reproduce established protocols for entanglement of exchange in quantum communications. However, the AI tool continued to produce a much more simple method of achieving quantum entanglement of photons.

“The authors have been able to train a neural network of complex data that describe how you set up this type of experiment in many different conditions and the network actually learns the physics behind it.” Sofia ValekorsaResearch physicist about the quantum technology initiative in CERNAnyone who has not participated in the new survey, told Live Science.
Eavesdropping in AI to simplify quantum tangling
The AI instrument suggested that the entrance appeared, as the path of photons is indistinguishable: when there are several possible sources from which photons could come, and if their origin becomes indistinguishable from each other, then an entanglement between them can be produced when no one exists before.
Although scientists were initially skeptical of the results, the instrument continued to return the same solution, so they tested the theory. By correcting the sources of photons and ensuring that they are indistinguishable, physicists create conditions in which the discovery of photons on certain paths ensures that others appear entangled.
This breakthrough in quantum physics simplifies the process by which quantum tangles can be formed. In the future, this could have consequences for quantum networks used for secure messages, which makes these technologies much more essential.
“The more we can rely on simple technology, the more we can increase the range of applications,” Valekorsa said. “The ability to build more sophisticated networks that could branch in different geometries can have a great influence on the case of one end to the end.”

Whether it is practical to scale the technology in a commercial viable process, it remains to be seen, since the noise of the environment and the imperfections of the device can cause instability in the quantum system.
The new survey also provided a convincing argument for the use of AI as a research instrument by physicists. “We are looking for more to present AI, but there is still a little skepticism, most of all because of what will be the role of physics after we start walking that way,” Valekorsa said. “This is an opportunity to achieve a very interesting result and shows in a very convincing way how it can be an instrument that physicists use.”
