Mode invisibility as a quantum nondemolition measurement of coherent light
Marvellous Onuma-Kalu, Robert B. Mann, Eduardo Martín-Martínez · Physical Review A · 2014
We exploit geometric properties of quantum states of light in optical cavities to carry out quantum nondemolition measurements. We generalize the ``mode-invisibility'' method to obtain information about the Wigner function of a squeezed coherent state in a nondestructive way. We also simplify the application of this nondemolition technique to measure single-photon and few-photon states.
