Abstract

With photon-number resolving detectors, we show compression of interference fringes with in- creasing photon numbers for a Fabry-P erot interferometer. This feature provides a higher precision in determining the position of the interference maxima compared to a classical detection strategy. We also theoretically show supersensitivity if N-photon states are sent into the interferometer and a photon-number resolving measurement is performed.
