Abstract
In this talk, we report the experimental demonstration of direct and efficient verification of entanglement between two multimode-multiphoton systems (one photon in three modes and two photons in three modes) using just two sets of classical correlation tables with and without a discrete Fourier transformation of the optical modes, clearly demonstrating a dramatic reduction in the resources required for entanglement verification. We will also report a novel method to produce a multi-photon parallel state efficiently with reducing excess photon components using multiple heralding single photon sources and N x N active optical switch.
