We explore the Quantum World using conductors whose size is so small that electrons behave as matter wave. The wave property of electrons gives rise to quantum interference which manifest as oscillations of the conductance versus a phase difference. Their dual particle property is observable in current fluctuations called quantum shot noise. Combined with clean ideal conductors our experiments adressed the most advanced problems in ELECTRON QUANTUM OPTICS. On-demand injection of electrons analogous to single photon sources let us envisage to perform simple quantum information tasks.
