Correlation functions and matrix permanents
Vincenzo Tamma, Florian Nägele · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2013
The connection between the boson sampling problem in a linear optical interferometer with single photon sources and the computation of matrix permanents has recently brought a strong interest for quantum computing applications. In this work we explore the physics of N-order interference in terms of N-order correlation functions in a generic linear optical interferometer with both Fock states sources and thermal sources. We will show how also in this case the connection of such a problem with matrix permanents play a fundamental role.
