An Efficient Routing Protocol for Quantum Key Distribution Networks

Entropy, 2022
Quantum key distribution (QKD) can provide point-to-point information-theoretic secure key services for two connected users. In fact, the development of QKD networks needs more focus from the scientific community in order to broaden the service scale of ...

Security of device-independent quantum key distribution protocols: a review [PDF]

Quantum, 2023
Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key exchange protocol in terms of security, as it can be performed securely with uncharacterised black-box devices.

Cost-Optimization-Based Quantum Key Distribution over Quantum Key Pool Optical Networks

Entropy, 2023
The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks ...

High-speed integrated QKD system [PDF]

, 2023
Quantum key distribution (QKD) is nowadays a well-established method for generating secret keys at a distance in an information-theoretically secure way, as the secrecy of QKD relies on the laws of quantum physics and not on computational complexity.
