    "abstract": "We compare the performance of various quantum key distribution (QKD) systems\nusing a novel single-photon detector, which combines frequency up-conversion in\na periodically poled lithium niobate (PPLN) waveguide and a silicon avalanche\nphotodiode (APD). The comparison is based on the secure communication rate as a\nfunction of distance for three QKD protocols: the Bennett-Brassard 1984 (BB84),\nthe Bennett, Brassard, and Mermin 1992 (BBM92), and the coherent differential\nphase shift keying (DPSK). We show that the up-conversion detector allows for\nhigher communication rates and longer communication distances than the commonly\nused InGaAs/InP APD for all the three QKD protocols.",
