Multi photon correlations in a multichannel network

We study the random walk of multiple photons in a massively multichannel system. The network consists of 3300 nearest-neighbour coupled silicon nitride waveguides embedded in silica. The photon correlations arising from the quantum interference between multiple single photons is measured using an intensified CCD at the output of the network. We further aim to control the multiphoton correlations in the network by structuring the incident states of quantum light. This procedure enables a versatile platform for studying quantum correlations, such as multiphoton boson sampling, without modifying the physical system. We will report on the latest progress in this experiment
