Architectures for QKD networks

Pirandola S. “Architectures for QKD networks”. In: Proceedings Volume 12243, Photonics for Quantum 2022; 1224309 (2022), doi: 10.1117/12.2635711

In this general brief overview, we discuss the different types of nodes and associated levels of security that can be considered in a quantum key distribution (QKD) network. This classification lead to different possible scenarios for QKD repeater chains and, more generally, for QKD network architectures.
