Multi-photon interferences with indistinguishable photons from independent light sources are at the focus of current research owing to their potential in optical quantum computing, creating remote entanglement and metrology. For example, multi-photon interferences from independent, uncorrelated emitters - either classical or non-classical - can be used to obtain enhanced resolution in imaging allowing to overcome the resolution limit of classical microscopy [1,2]. The approach can be considered an extension of the celebrated Hanbury Brown and Twiss experiment [3], exploring however spatial intensity correlations of order N > 2.
