    "abstract": "Quantum Cryptography over 23km of installed Telecom fiber using a novel\ninterferometer with Faraday mirrors is presented. The interferometer needs no\nalignment nor polarization control and features 99.8% fringe visibility. A\nsecret key of 20kbit length with a error rate of 1.35% for 0.1 photon per pulse\nwas produced.",
