Auxiliary graph based routing, wavelength, and time-slot assignment in metro quantum optical networks with a novel node structure

2020 · Optics Express

Nowadays, critical sectors in government, finance, and military are facing increasingly high security challenges. However, traditional public-key crypto-systems based on computational complexity are likely to suffer from upgrade computational power. Quantum key distribution (QKD) is …

Topological Mapping based Failure Recovery in Multi-domain Quantum Key Distribution Networks

2021 · 26th Optoelectronics and Communications Conference

This paper proposes a topological mapping based failure recovery algorithm in multi-domain quantum key distribution networks. Simulation results show that the algorithm can achieve good performance in terms of success rate of service recovery under …

Topology Abstraction-Based Routing Scheme for Secret-Key Provisioning in Hybrid GEO/LEO Quantum Satellite Networks

2023 · Entropy

Quantum key distribution (QKD) is a promising technique to resist the threat against quantum computers. However, the high loss of quantum signals over a long-distance optical fiber is an obstacle for QKD in the intercontinental …
