Multiuser quantum key distribution using wavelength division multiplexing

Gilles Brassard A, Félix Bussières, Nicolas Godbout +1 more

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.

Quantum key distribution integration with optical dense wavelength division multiplexing: a review

Arash Bahrami, Andrew Lord, Timothy P. Spiller

Quantum key distribution (QKD) can ensure information security between two remote parties. To commercialise QKD technology successfully, it should be integrated with dense wavelength division multiplexing optical transport. However, various challenges limit the QKD's performance in terms of the quantum key rate, quantum bit error rates, and maximum achievable distance. In this study, the authors discuss some of the major practical limiting factors for QKD performance such as spontaneous Raman scattering, four‐wave mixing, and amplified spontaneous emission.

Hacking Quantum Key Distribution over Space Division Multiplexing System

Chao Lei, Paolo Monti A, Rui Lin

On the one hand, Quantum key distribution (QKD) offers unparalleled security relying on the principles of quantum mechanics. On the other hand, space division multiplexing (SDM) is recognized as the route toward a capacity upgrade for current core optical communication networks and will progressively permeate into shorter-reach networks. Incorporating QKD into classical networks, with SDM being one of its components, will enhance data communication security. Understanding the security implications of implementing QKD over SDM is crucial for the practical deployment of quantum-secure communication technologies, especially in scenarios where high data capacity and multiplexing techniques are essential. In this paper, we study a QKD eavesdropping use case where connectivity is provided via SDM fibers. Specifically, we discuss the detector blinding attack (DBA) concerning inter-core crosstalk in an entanglement based QKD system. Additionally, we analyze the blinding power of DBA over quasi-homogeneous and heterogeneous seven-core fiber scenarios. Furthermore, the potential countermeasures to mitigate the impact of such attacks are discussed.
