摘要：
A quantum key distribution system based on photon pairs entangled in energy-time and optimized for long distance transmission is presented. It is based on a Franson arrangement for monitoring quantum correlations, and uses a protocol analogous to BB84. Passive state preparation is implemented by polarization multiplexing in the interferometers. We distributed a sifted key of 0.4 Mbits at a raw rate of 134 Hz and with an error rate of 8.6% over a distance of 8.5 kilometers.
