    "abstract": "An improved quantum key distribution test system operating at clock rates of\nup to 2GHz using a specially adapted commercially available silicon single\nphoton avalanche diode is presented. The use of improved detectors has improved\nthe fibre-based test system performance in terms of transmission distance and\nquantum bit error rate.",
