We propose a new approach towards quantum information processing using multi-photon interferometers with thermal as well as non-classical light sources.
The emergence of a second-order interference effect which takes advantage of the correlation between specific interferometer paths with each other is demonstrated in [1]. This effect could be experimentally useful for simulations of small-scale quantum circuits and applications in high-precision metrology and imaging.
Furthermore, we present a general formalism to describe the correlation function of an arbitrary multi-photon interferometer. The obtained structure allows an interpretation in terms of bipartite graphs, giving both a great insight into the physics of such setups, as well as enabling reverse engineering of those.
