Abstract
Quantum cryptography over 23km of installed telecommunications fibre u sing a novel interferometer with Faraday mirrors is presented. The int erferometer needs no alignment nor polarisation control and features 9 9.8% fringe visibility. A secret key of 20kbit length an error rate of 1.35% for 0.1 photon per pulse was produced.
