    "abstract": "We use a photon-number resolving detector to monitor the photon number\ndistribution of the output of an interferometer, as a function of phase delay.\nAs inputs we use coherent states with mean photon number up to seven. The\npostselection of a specific Fock (photon-number) state effectively induces\nhigh-order optical non-linearities. Following a scheme by Bentley and Boyd\n[S.J. Bentley and R.W. Boyd, Optics Express 12, 5735 (2004)] we explore this\neffect to demonstrate interference patterns a factor of five smaller than the\nRayleigh limit.",
