Alain Aspect was awarded the 2022 Nobel Prize in Physics, jointly with John Clauser and Anton Zeilinger, for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.

Alain was a member of the EQUS Scientific Advisory Board for ten years. During this time, he was CNRS research director and professor at the Institut d’Optique Graduate School (“SubOptique”), and at the Ecole Polytechnique. He led the Quantum Gas group at the Charles Fabry Laboratory (Institut d’Optique/CNRS). Among his many contributions to the fields of quantum optics and atomic optics, the fundamental experiments carried out by his team in 1982 at the Charles Fabry Laboratory were particularly notable. These experiments confirmed the revolutionary nature of quantum entanglement, which Einstein had intuited, and whose experimental demonstration was made possible by the theoretical work of John Bell. These results paved the way for research into quantum information and the development of technologies such as quantum cryptography and quantum computing.
