Abstract

The performance of four passive optical network topologies in implementing multi-user quantum key distribution is compared. The networks considered are the passive-star network, the optical-ring network based on the Sagnac interferometer, the wavelength-routed network, and the wavelength-addressed bus network. An analysis of the quantum bit-error rate and sifted key rate for each of these topologies is used to determine their suitability for providing service to networks of various sizes.

In this paper, we explore the performance of two network topologies: the optical ring network based on the Sagnac Interferometer and the wavelength routed optical network. The performance of all three networks for multiuser quantum key distribution are then computer simulated and compared by quantum bit error rate (QBER) analysis. To the best of our knowledge, this is the first time system level analysis have been performed on the suitability of various optical networks for quantum key distribution.

Quantum cryptography applies the uncertainty principle and the no-cloning theorem of quantum mechanics to provide ultra-secure encryption key distribution between two parties. Present quantum cryptography technologies provide encryption key distribution between two parties. However, practical implementations encryption key distribution schemes require establishing secure quantum communications amongst multiple users. In this talk, we survey some of the state of the art quantum encryption deployment in communication networks. We will also discuss some common topologies that are being considered for multi-user quantum encryption networks. The performance of the multi-user quantum key distribution systems is then compared for four different optical network topologies: the Sagnac-based fiber ring, the wavelength routed, the passive star and the bus network. Their performances are compared and analyzed using quantum bit error rate analysis.

Comparison of quantum key distribution over fiber optics network topologies

Eric Donkor

We present the characteristic performance of quantum key distribution over various fiber optic network topologies. The networks include the RING, BUS, and STAR. Quantum bit-error 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 model is compared with experiment results for bus network architecture for quantum key distribution.
