Paper Abstract

An experimental setup for quantum key distribution (QKD) in special optical fiber at the wavelength of 850nm was presented. The system employs the B92 protocol to establish a secret key between Alice and Bob. The key is encoded in the phase of very weak laser of average photon number 0.1 per pulse. The measured error rate is lower than 8%, the effective transmission rate is about 17bit/s.
