Alain Aspect, (born June 15, 1947, Agen, France), French physicist who was awarded the 2022 Nobel Prize for Physics for his experiments with quantum entanglement. He shared the prize with American physicist John F. Clauser and Austrian physicist Anton Zeilinger. What happens to one particle in an entangled pair determines what happens to the other, even if they are really too far apart to affect each other. The laureates’ development of experimental tools has laid the foundation for a new era of quantum technology. Aspect received a bachelor’s degree from the École Normale Supérieure de Cachan (ENS Cachan), passing his
