The Royal Swedish Academy of Sciences has decided to award the 2022 Nobel Prize Physics to Alain Aspect, John F. Clauser and Anton Zeilinger,” they said today.
Frenchman Alain Aspect, American John Clauser and Austrian Anton Zeilinger have distinguished themselves with their discoveries in the field of “the power of quantum mechanics,” said the secretary general of the Royal Swedish Academy of Sciences at the Karolinska Institute in Stockholm.
The Nobel jury said the three researchers, pioneers in the study of the revolutionary mechanisms of quantum physics, have been recognized for their groundbreaking work on “quantum entanglement,” a state of matter in which two particles are perfectly correlated, regardless of the distance between them. them. .
“Quantum informatics is a dynamic and rapidly evolving field,” said Eva Olsson, a member of the Nobel Committee, explaining that it “has wide and potential implications in areas such as the secure transmission of information (data encryption), quantum computing, and discovery.” technology”.
Eva Olson said that while physicists often solve problems that at first glance seem far removed from everyday concerns—tiny particles and the vast mysteries of space and time—their research provides the basis for many of the practical applications of science.
This complex and sometimes illogical mechanics, the study of which is now awarded, was predicted by quantum theory, but not even Albert Einstein believed in it, in the existence of two particles connected at the beginning, like twins, capable of maintaining a mark of their common past and having a similar and coordinated behavior at a distance.
Alain Aspect, associated with the French University of Paris-Saclay, is 75, John Clauser is 79 and Anton Zeilinger of the University of Vienna is 77.
According to the Academy, the laureates have “performed pioneering experiments using entangled quantum states, in which two particles behave as one even when separated. The results have paved the way for new technologies based on quantum information.”
Anton Zeilinger’s research team “demonstrated a phenomenon called quantum teleportation, which allows a quantum state to be moved from one particle to another at a distance.”
In turn, Alain Aspect “designed a configuration to close an important gap. He was able to change the definitions of the dimension after the entangled pair left their source, so the definition that existed at the time they were issued could not affect the result.”
John Clauser “created a device that simultaneously emitted two entangled photons, each of which was directed to a filter that checked its polarization. The result was a clear violation of Bell’s inequality and agreement with the predictions of quantum mechanics.”
Last year, the Nobel Prize in Physics was awarded to three scientists, Shukuro Manabe, Klaus Hasselmann and Giorgio Parisi, whose work helped explain and predict the complex forces of nature, contributing to the understanding of climate change.
prize Medicine Yesterday the Nobel Prize week began, today followed by the prize in physics, on Wednesday – in chemistry, and on Thursday – in literature. The 2022 Nobel Peace Prize will be announced on Friday, while the Economics Prize will be announced on October 10.
The Nobel Prizes were born out of the desire of the Swedish scientist and industrialist Alfred Nobel (1833-1896) to bequeath the bulk 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 amount to ten million Swedish kronor (over 953,000 euros).
