    "abstract": "We demonstrate a robust, compact and automated quantum key distribution\nsystem, based upon a one-way Mach-Zender interferometer, which is actively\ncompensated for temporal drifts in the photon phase and polarization. The\nsystem gives a superior performance to passive compensation schemes with an\naverage quantum bit error rate of 0.87% and a duty cycle of 99.6% for a\ncontinuous quantum key distribution session of 19 hours over a 20.3km installed\ntelecom fibre. The results suggest that actively compensated QKD systems are\nsuitable for practical applications.",
