Mode invisibility as a quantum non-demolition measurement of coherent light
arXiv:1404.0726 · doi:10.1103/PhysRevA.90.033847
Abstract
We exploit geometric properties of quantum states of light in optical cavities to carry out quantum non-demolition measurements. We generalize the 'mode invisibility' method to obtain information about the Wigner function of a squeezed coherent state in a non-destructive way. We also simplify the application of this non-demolition technique to measure single-photon and few-photon states.
