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.

Integrating QKD in telecommunication networks [PDF]
, 2010 To date, QKD development has mostly focused in non-shared point-to-point links. Despite its limitations, this is the only technology commercially available today, and this makes it even more expensive and not easily deployable. The integration of QKD with the commercial network infrastructure would open the possibility of a scalable deployment and ...
