    "abstract": "We present a method for computing the action of conditional linear optical\ntransformations, conditioned on photon counting, for arbitrary signal states.\nThe method is based on the Q-function, a quasi probability distribution for\nanti normally ordered moments. We treat an arbitrary number of signal and\nancilla modes. The ancilla modes are prepared in an arbitrary product number\nstate. We construct the conditional, non unitary, signal transformations for an\narbitrary photon number count on each of the ancilla modes.",
