    "abstract": "Detectors that can resolve photon number are needed in many quantum\ninformation technologies. In order to be useful in quantum information\nprocessing, such detectors should be simple, easy to use, and be scalable to\nresolve any number of photons, as the application may require great portability\nsuch as in quantum cryptography. Here we describe the construction of a\ntime-multiplexed detector, which uses a pair of standard avalanche photodiodes\noperated in Geiger mode. The detection technique is analysed theoretically and\ntested experimentally using a pulsed source of weak coherent light.",
