Source attack of decoy-state quantum key distribution using phase information [PDF]
, 2013 Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commercialization, but many practical QKD systems still suffer from security ...

On High-Dimensional Twin-Field Quantum Key Distribution [PDF]
QuantumTwin-Field Quantum Key Distribution (QKD) is a QKD protocol that uses single-photon interference to perform QKD over long distances. QKD protocols that encode information using high-dimensional quantum states can benefit from increased key rates and ...

Measurement-device-independent quantum communication with an untrusted source [PDF]
, 2015 Measurement-device-independent quantum key distribution (MDI-QKD) can provide enhanced security, as compared to traditional QKD, and it constitutes an important framework for a quantum network with an untrusted network server.

Effects of experimental impairments on the security of continuous-variable quantum key distribution
Heliyon, 2023 Quantum Key Distribution (QKD) is a cutting-edge communication method that enables secure communication between two parties. Continuous-variable QKD (CV-QKD) is a promising approach to QKD that has several advantages over traditional discrete-variable ...

MDI-QKD: Continuous- versus discrete-variables at metropolitan distances [PDF]
, 2015 In a comment, Xu, Curty, Qi, Qian, and Lo claimed that discrete-variable (DV) measurement device independent (MDI) quantum key distribution (QKD) would compete with its continuous-variable (CV) counterpart at metropolitan distances. Actually, Xu et al.'s
