Towards a feedbacked down-conversion source for large complex quantum states — •Melanie Engelkemeier, Regina Kruse, Linda Sansoni, Sonja Barkhofen, and Christine Silberhorn — Universität Paderborn, Integrierte Quantenoptik, Warburger Str. 100, D-33098 Paderborn

In order to realise large photonic quantum states in large networks, we implement a PDC source in a feedback loop to generate time-multiplexed states. By the stimulated generation of photons, the probability to generate photon pairs is increased. We present the source design of a periodically poled KTP crystal [1] and simulations of the setup to outline losses and the stimulation in the system. Furthermore, we will investigate the possibilities to generate complex time-bin correlated states.
