    "abstract": "We report on a complete experimental implementation of a quantum key\ndistribution protocol through a free space link using polarization-entangled\nphoton pairs from a compact parametric down-conversion source. Over 10 hours of\nuninterrupted communication between sites 1.5 km apart, we observe average key\ngeneration rates of 630 per second after error correction and privacy\namplification. Our scheme requires no specific hardware channel for\nsynchronization apart from a classical wireless link, and no explicit random\nnumber generator.",
