Practical aspects of measurement-device-independent quantum key distribution [PDF]

New Journal of Physics, 2013
A novel protocol, measurement-device-independent quantum key distribution (MDI-QKD), removes all attacks from the detection system, the most vulnerable part in QKD implementations.

On the Discretized Gaussian Modulation (DGM)- Based Continuous Variable-QKD

IEEE Access, 2019
To overcome the low reconciliation efficiency problem of Gaussian modulation (GM)-based-continuous variable (CV)-quantum key distribution (QKD), in this paper, we propose to use discretized GM (DGM)-based-CV-QKD. The proposed CV-QKD scheme has complexity

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 ...
