More Information
Summary:The photon counting is an important task in quantum optics and photonic quantum information. The simplest photon counter found in the literature is a multi-photon number resolving detector (MPNRD), composed by a threshold single-photon detector and a time-multiplexing scheme usually built with a fiber ring. The correct photon number estimation is hampered by the optical losses and the non-unit quantum efficiency of the single-photon detector used. In this work we provide an analytical expression that improves the performance of the multi-photon number resolving detector when coherent states are measured. This transform the static MPNRD device in a dynamic MPNRD.
