Interferometry with a photon-number resolving detector

ORAL

Abstract

In this contribution, we present our studies of Michelson and Fabry-Perot interferometers with a photon-number resolving detector. We show experimentally that with a weak coherent light beam, the use of a photon-number resolving detector leads to a compression of the interference fringes. We also discuss how to improve the sensitivity of interferometers below the shot-noise limit by using nonclassical light and photon-number resolving detectors.
