High precision interferometry with a transition edge sensor

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 improves the interferometric resolution. We also discuss ways the sensitivity of interferometers can be further improved beyond the standard quantum limit by using nonclassical light and photon-number resolving detectors. ~
