Paper Abstract

Quantum cryptography, or more specifically, quantum key distribution (QKD), has attracted a lot of attention in the recent years with the discovery that it can provide absolute secrecy for communications. We propose a new architecture for implementing a fiber-based network of quantum key distribution using optical wavelength division multiplexing in the fiber. We discuss the advantages over previous proposals and we report experimental work demonstrating the feasibility of the proposed architecture.
