Abstract

We present and compare the characteristic performance of single-photons, correlatedphotons, and entangled-photons for quantum key distribution over various fiber optic network topologies. The networks include the RING, BUS, and STAR. Quantum biterror rate is determined for each network as function of number of users, and transmission distance. The trade-off between number of users and transmission distance is presented. The robustness of the QKD against eavesdropping is evaluated for each architecture.
