    "abstract": "We present a scheme for non-deterministically approximating photon number\nresolving detectors using non-discriminating detectors. The model is simple in\nconstruction and employs very few physical resources. Despite its\nnon-determinism, the proposal may nonetheless be suitable for use in some\nquantum optics experiments in which non-determinism can be tolerated. We\nanalyze the detection scheme in the context of an optical implementation of the\ncontrolled-NOT gate, an inherently non-deterministic device. This allows the\ngate\u0027s success probability to be traded away for improved gate fidelity,\nassuming high efficiency detectors. The scheme is compared to two other\nproposals, both deterministic, for approximating discriminating detectors using\nnon-discriminating detectors: the cascade and time division multiplexing\nschemes.",
