    "abstract": "The Visible Light Photon Counter (VLPC) features high quantum efficiency and\nlow pulse height dispersion. These properties make it ideal for efficient\nphoton number state detection. The ability to perform efficient photon number\nstate detection is important in many quantum information processing\napplications, including recent proposals for performing quantum computation\nwith linear optical elements. In this paper we investigate the unique\ncapabilities of the VLPC. The efficiency of the detector and cryogenic system\nis measured at 543nm wavelengths to be 85%. A picosecond pulsed laser is then\nused to excite the detector with pulses having average photon numbers ranging\nfrom 3-5. The output of the VLPC is used to discriminate photon numbers in a\npulse. The error probability for number state discrimination is an increasing\nfunction of the number of photons, due to buildup of multiplication noise. This\nputs an ultimate limit on the ability of the VLPC to do number state detection.\nFor many applications, it is sufficient to discriminate between 1 and more than\none detected photon. The VLPC can do this with 99% accuracy.",
