Hanbury Brown-Twiss, Hong-Ou-Mandel, and other landmarks in quantum optics: from photons to atoms
Presented by Alain Aspect, Laboratoire Charles Fabry, Institut d’Optique Graduate School
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 HBT [1] and HOM effects [2] , we are progressing towards a test of Bell's inequalities with pairs of momentum entangled atoms [3] .
