    "abstract": "The performance of nondeterministic nonlinear gates in linear optics relies\non the photon counting scheme being employed and the efficiencies of the\ndetectors in such schemes. We assess the performance of the nonlinear sign\ngate, which is a critical component of linear optical quantum computing, for\ntwo standard photon counting methods: the double detector array and the visible\nlight photon counter. Our analysis shows that the double detector array is\ninsufficient to provide the photon counting capability for effective\nnondeterministic nonlinear transformations, and we determine the gate fidelity\nfor both photon counting methods as a function of detector efficiencies.",
