Alain Aspect, 2022 Nobel Prize in Physics
Alain Aspect, a research professor emeritus at the CNRS, professor at the Institut d’Optique Graduate School/Université Paris-Saclay, ENS Paris-Saclay, and École polytechnique, as well as member of the Charles Fabry Laboratory (Institut d’Optique Graduate School/CNRS, Université Paris-Saclay), is the winner of the 2022 Nobel Prize in Physics. He shares this distinction with John F. Clauser of the United States and Anton Zeilinger of Austria for their pioneering research on quantum entanglement, which paved the way for quantum technology.
The award recognises a lifetime of revolutionary research in the field. Alain Aspect distinguished himself in 1982 by clearly revealing the fundamental quantum property of quantum entanglement. By precisely studying a controlled light source, he irrefutably established the phenomenon of quantum entanglement, and provided an experimental answer to the EPR paradox proposed fifty years earlier by Albert Einstein, Boris Podolsky, and Nathan Rosen. He also demonstrated the violation of Bell inequalities established a few years earlier. This discovery showed the capacity of two photons to behave as a single quantum system, even at a distance from each other, as long as they had interacted in the past. This was a major breakthrough that paved the way for the new field of quantum technology, which today is revolutionising the processing and communication of information.
