Evaluating Relayed and Switched Quantum Key Distribution (QKD) Network Architectures

Journal of Lightwave Technology
We evaluate the performance of two architectures for network-wide quantum key distribution (QKD): Relayed QKD, which relays keys over multi-link QKD paths for non-adjacent nodes, and Switched QKD, which uses optical switches to dynamically connect arbitrary QKD modules to form direct QKD links between them.
