Title

Wave Particle Duality for a Single Photon

Abstract

Since the early days of quantum mechanics, and still in Feynman’s lectures on physics, interference between spatially separated trajectories of a single particle has not ceased to fascinate physicists. I will present a realization in optics of that Gedanken-Experiment, realized with a true single photon source. It has even allowed us to implement the Wheeler’s delayed choice experiment, emphasizing the weirdness of wave particle duality for a single particle.
