Analysis of Multiple Overlapping Paths algorithms for Secure Key Exchange in Large-Scale Quantum Networks. (arXiv:2205.03174v1 [quant-ph])

Quantum networks open the way to an unprecedented level of communication
security. However, due to physical limitations on the distances of quantum
links, current implementations of quantum networks are unavoidably equipped
with trusted nodes. As a consequence, the quantum key distribution can be
performed only on the links. Due to this, some new authentication and key
exchange schemes must be considered to fully benefit from the unconditional
security of links. One such approach uses Multiple Non-Overlapping Paths
(MNOPs) for key …
