    "abstract": "Photon number resolving detectors are needed for a variety of applications\nincluding linear-optics quantum computing. Here we describe the use of\ntime-multiplexing techniques that allows ordinary single photon detectors, such\nas silicon avalanche photodiodes, to be used as photon number-resolving\ndetectors. The ability of such a detector to correctly measure the number of\nphotons for an incident number state is analyzed. The predicted results for an\nincident coherent state are found to be in good agreement with the results of a\nproof-of-principle experimental demonstration.",
