    "abstract": "We present a time-multiplexed interferometer based on Faraday mirrors, and\napply it to quantum key distribution. The interfering pulses follow exactly the\nsame spatial path, ensuring very high stability and self balancing. Use of\nFaraday mirrors compensates automatically any birefringence effects and\npolarization dependent losses in the transmitting fiber. First experimental\nresults show a fringe visibility of 0.9984 for a 23km-long interferometer,\nbased on installed telecom fibers.",
