The 2022 Nobel Prize in Physics goes to Frenchman Alain Aspect, an American and an Austrian for their work on the quantum revolution

The 2022 Nobel Prize in Physics has been awarded to Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger, the Royal Academy of Sciences announced on Tuesday (October 4).

The trio of 70-year-olds will be rewarded for their discoveries on quantum entanglement, a mechanism by which two quantum particles are perfectly correlated regardless of the distance separating them, the Nobel jury announced.

The demonstration of this amazing property has paved the way for new technologies in quantum computing and ultra-secure communications, or even ultra-sensitive quantum sensors that would enable extremely precise measurements like those of gravity in space.

These enigmatic mechanics were predicted by quantum theory. But even Albert Einstein didn’t believe it: Two initially connected particles – like twins could be – could keep traces of their common past and behave similarly at a distance.

Alain Aspect, who belongs to the French University of Paris-Saclay and the Ecole polytechnique, is 75 years old, while John Clauser is 79 and Anton Zeilinger from the University of Vienna is 77 years old. The trio is rewarded “for his experiments with entangled photons, which demonstrate violations of Bell’s inequalities and open a groundbreaking path to quantum computing”, according to the Nobel jury. And to continue: “Alain Aspect, John Clauser and Anton Zeilinger have each performed pioneering experiments with entangled quantum states, in which two particles behave as one even when separated. »

In 2021, climate change modeling will be rewarded

Last year’s prize, awarded by the Swedish Academy of Sciences, went to two climate modeling experts, the American-Japanese Syukuro Manabe and the German Klaus Hasselmann, and the Italian Giorgio Parisi, a specialist in complex physical systems.

Like the business prize and other science prizes, the Nobel Prize in Physics suffers from a shortage of female laureates, but few women’s names are among the speculations this year. Since the awards were established in 1901, only four women have won in physics, most recently American astrophysicist Andrea Ghez two years ago.
