    "abstract": "We present a quantum key distribution experiment in which keys that were\nsecure against all individual eavesdropping attacks allowed by quantum\nmechanics were distributed over 100 km of optical fiber. We implemented the\ndifferential phase shift quantum key distribution protocol and used low timing\njitter 1.55 um single-photon detectors based on frequency up-conversion in\nperiodically poled lithium niobate waveguides and silicon avalanche\nphotodiodes. Based on the security analysis of the protocol against general\nindividual attacks, we generated secure keys at a practical rate of 166 bit/s\nover 100 km of fiber. The use of the low jitter detectors also increased the\nsifted key generation rate to 2 Mbit/s over 10 km of fiber.",
