We report a differential phase shift quantum key distribution (DPS-QKD) experiment in the 1.3-μm band that uses single photon detectors based on a frequency up-conversion technique. By combining a fast-clock DPS-QKD and up-conversion detectors operated in a non-gated mode, we have achieved a sifted key rate of 180 kbit/s over 10 km of fiber, which is one order of magnitude larger than a previously reported 1.3-μm band result.
