Security analysis of orthogonal state attack on a high-speed quantum key distribution system
Jialei Su, Qingquan Peng, Jia-lin Chen +6
High-speed quantum key distribution (QKD) systems have achieved repetition frequencies above gigahertz through advanced technologies and devices, laying an important foundation for…
Quantifying the Upper Limit of Backflash Attack in Quantum Key Distribution
Jialei Su, Junxuan Liu, Zihao Chen +6
Quantum key distribution (QKD) provides information-theoretic security grounded in the fundamental laws of physics. Nevertheless, practical imperfections can introduce side channel…
Spectral side channels in quantum key distribution under laser damage
Binwu Gao, Junxuan Liu, Ekaterina Borisova +8
In the transmitter of a quantum key distribution (QKD) system, a dense wavelength-division multiplexer (DWDM) is typically used to combine quantum and synchronization signals and i…
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…
