Alain Aspect is a professor at the Institut d'Optique - Université Paris-Saclay and École Polytechnique, and an emeritus senior researcher at CNRS. A graduate of ENS Paris-Saclay and Orsay University, he is renowned for his groundbreaking experiments testing the foundations of quantum mechanics, particularly Bell's inequalities - work that earned him the 2022 Nobel Prize in Physics alongside John Clauser and Anton Zeilinger. His research spans from single-photon experiments to laser cooling of atoms, and later to atomic quantum optics and quantum simulators with degenerate gases. He is a member of the Académie des Sciences, Académie des Technologies, and several international academies.
