About :
???? Les Mardis de l'Espace des sciences ???? https://www.espace-sciences.org/renne... The first quantum revolution is based on the concept of wave-particle duality, discovered by Albert Einstein and Louis de Broglie. It made it possible to elucidate the structure of matter in its most subtle aspects and enabled the invention of the transistor, the laser and computer circuits, the basis of the information and communication society. The second quantum revolution is first based on the concept of entanglement, exposed by the quasi-philosophical debate between Einstein and Niels Bohr, which began in 1935. The extraordinary nature of this concept was confirmed by experimental tests of Bell's inequalities, highlighted by the 2022 Nobel Prize in Physics awarded to Alain Aspect, John Clauser and Anton Zeilinger. Entanglement and the development of methods for controlling single quantum objects are used in various developing technologies, from information to metrology, including quantum computers. With Alain Aspect, Professor at the Institut d'Optique-Université Paris-Saclay and at the École Polytechnique. Nobel Prize in Physics 2022, he is a member of the French Academy of Sciences and the French Academy of Technologies. ????
