Alain Aspect

Alain Aspect was born on June 15, 1947 in Agen, France. He received his master’s and Ph.D. degrees from Université d'Orsay in 1971 and 1983.

He is known for his experiments illuminating the most intriguing properties of quantum mechanics. His Bell's inequalities tests with pairs of entangled photons (1982) have contributed to settle a debate between Albert Einstein and Nils Bohr, started in 1935. He has also, with Philippe Grangier, given a striking demonstration of wave-particle duality for a single photon, and realized the Wheeler's delayed choice experiment.

Aspect is the recipient of the 2013 Frederic Ives Medal, the 2012 Herbert Walther Award, and the 1999 Max Born Award from OSA. He has been an OSA Fellow since 2000.
