    "abstract": "We provide a general approach for the analysis of optical state evolution\nunder conditional measurement schemes, and identify the necessary and\nsufficient conditions for such schemes to simulate unitary evolution on the\nfreely propagating modes. If such unitary evolution holds, an effective photon\nnonlinearity can be identified. Our analysis extends to conditional measurement\nschemes more general than those based solely on linear optics.",
