    "abstract": "A multichannel detector has been constructed using a single avalanche\nphotodiode and a fiber-loop delay line. Detection probabilities of the channels\ncan be set using a variable-ratio coupler. The performance of the detector is\ndemonstrated on its capability to distinguish multi-photon states (containing\ntwo or more photons) from the one-photon state and the vacuum state.",
