The second quantum revolution is based on entanglement, discovered by Einstein and Schrödinger in 1935. Its extraordinary character has been experimentally demonstrated by landmark experiments in quantum optics.

At Institut d’Optique, we are currently revisiting these landmarks using atoms instead of photons, and after the observation of the atomic HOM effect (1), we are progressing towards a test of Bell’s inequalities with pairs of momentum entangled atoms (2).
