Parameter estimation of time and frequency shifts with generalized Hong-Ou-Mandel interferometry
Nicolas Fabre, Simone Felicetti
Abstract
Hong-Ou-Mandel (HOM) interferometers can detect time delays down to attoseconds using two-photon destructive interference. Here, the authors present a theoretical extension of HOM interferometry with various spectral distributions of the probe states, and find that periodic continuous-variable grid states can be engineered with currently-available technology that significantly outperform the resolution of time-frequency Gaussian states.
