Measuring nonclassicality with Silicon photomultipliers

Abstract

Detector stochastic deviations from an ideal response can hamper the measurement of quantum properties of light especially in the mesoscopic regime where photon-number resolution is required. We demonstrate that, by a proper analysis of the output signal, nonclassicality of twin-beam states can be detected and exploited with commercial and cost effective silicon-based photon-number-resolving detectors.
