Abstract

A six-user quantum key distribution network based on the auto-compensating plug & play scheme is experimentally demonstrated. The network, which has a bus line topology, uses the BB84 protocol to transmit cryptographic keys encoded unto the phase states of highly attenuated laser light to distances of up to 30.9 km of standard telecommunication-grade fiber. Each user on the network is assigned a unique wavelength for communication with the network server. The quantum bit error rate and sifted key rate measured compares favorably with theory.
