The 2022 Nobel Prize in Physics has been awarded to Alain Asqect, John F. Clauser and Anton Zeilinger for work in quantum mechanics, the Swedish Academy announced today.

“The Royal Swedish Academy of Sciences has decided to award the 2022 Nobel Prize in Physics to Alain Aspect, John F. Clauser and Anton Zeilinger”, it was informed today.

Frenchman Alain Aspect, American John Clauser and Austrian Anton Zeilinger were distinguished for their discoveries on the “power of quantum mechanics”, announced the secretary general of the Royal Swedish Academy of Sciences at the Karolinska Institute in Stockholm.

The Nobel jury said that the three researchers, pioneers in the study of the revolutionary mechanisms of quantum physics, were distinguished for their pioneering work on “quantum entanglement”, a state of matter in which two particles are perfectly correlated, regardless of the distance between them. .

“Quantum information science is a vibrant and rapidly developing field,” said Eva Olsson, a member of the Nobel committee, explaining that it “has broad and potential implications in areas such as secure transfer of information (data encryption), quantum computing and detection technology”.

Eva Olson said that while physicists often tackle problems that seem at first glance to be far removed from everyday concerns – tiny particles and the vast mysteries of space and time – their research provides the foundation for many practical applications of science. science.

This complex and sometimes logic-defying mechanics, the study of which has now been awarded, was predicted by quantum theory, but not even Albert Einstein believed it, in the existence of two particles united at the beginning, like twins, that can keep the mark of their past common and have a similar and coordinated behavior at a distance.

Affiliated with the French University of Paris-Saclay, Alain Aspect is 75 years old, while John Clauser is 79 years old and Anton Zeilinger from the University of Vienna is 77 years old.

According to the Academy, the laureates “performed innovative experiments using entangled quantum states, where two particles behave as a single unit, even when they are separated. The results have paved the way for new technologies based on quantum information.”

Anton Zeilinger’s research group “demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to another at a distance.”

In turn, Alain Aspect “developed a configuration to close an important gap. He was able to change measurement definitions after an entangled pair had left its source, so the definition that existed when they were issued could not affect the result.” .

John Clauser “built a device that emitted two entangled photons at a time, each towards a filter that tested its polarization. The result was a clear violation of a Bell inequality and agreed with the predictions of quantum mechanics.” .

Last year, the Nobel Prize in Physics was awarded to three scientists – Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi – whose work helped explain and predict complex forces of nature, contributing to the understanding of climate change.

The Medicine prize started yesterday a week of Nobel Prize announcements, followed today by the Physics prize, with chemistry on Wednesday and literature on Thursday. The 2022 Nobel Peace Prize will be announced on Friday and the economics prize on October 10.

The Nobel Prizes were born from the will of the Swedish scientist and industrialist Alfred Nobel (1833-1896) to bequeath a large part of his fortune to people who work for “a better world”. The international prestige of the Nobel prizes is largely due to the amounts awarded, which currently reach ten million Swedish kronor (more than 953,000 euros).
