Characterization of Intensity Correlation via Single-photon Detection in Quantum Key Distribution
Tianyi Xing, Junxuan Liu, Likang Zhang +10
One of the most significant vulnerabilities in the source unit of quantum key distribution (QKD) is the correlation between quantum states after modulation, which shall be characte…

Intensity correlations in measurement-device-independent quantum key distribution
Junxuan Liu, Tianyi Xing, Ruiyin Liu +3
The intensity correlations due to imperfect modulation during the quantum-state preparation in a measurement-device-independent quantum key distribution (MDI QKD) system compromise…
