Spectral side channels of wavelength-division multiplexer 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 wavelength-division multiplexer (WDM) is typically used to combine quantum and synchronization signals and is direc…
Deep Anomaly Detection for Active Attacks on the Receiver in Quantum Key Distribution
Junxuan Liu, Bingcheng Huang, Jialei Su +2
Traditional countermeasures against attacks targeting the receiver in quantum key distribution (QKD) systems often suffer from poor compatibility with deployed infrastructure, the…
Optical-pumping attack on a quantum key distribution laser source
Maxim Fadeev, Anastasiya Ponosova, Qingquan Peng +3
We report a new type of vulnerability in practical implementations of quantum key distribution systems. We show that it is possible to increase the pulse energy of a source laser d…
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…
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…
Practical security of twin-field quantum key distribution with optical phase-locked loop under wavelength-switching attack
Qingquan Peng, Jiu-Peng Chen, Tianyi Xing +4
The twin-field class quantum key distribution (TF-class QKD) has experimentally demonstrated the ability to surpass the fundamental rate-distance limit without requiring a quantum…
