    "abstract": "A superconducting single-photon detector based on a niobium nitride nanowire\nis demonstrated in an optical-fibre-based quantum key distribution test bed\noperating at a clock rate of 3.3 GHz and a transmission wavelength of 850 nm.\nThe low jitter of the detector leads to significant reduction in the estimated\nquantum bit error rate and a resultant improvement in the secrecy efficiency\ncompared to previous estimates made by use of silicon single-photon avalanche\ndetectors.",
