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…
High-efficiency Weak-trace-free Counterfactual Communication via Quantum Zeno Effect
Tianyi Xing, Anqi Huang, Yizhi Wang +10
The quantum Zeno effect, which inhibits quantum state evolution via repeated weak measurements, significantly enhances the efficiency of interaction-free measurement (IFM). This fu…
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…
Pulsed laser attack at 1061 nm potentially compromises quantum key distribution
Anastasiya Ponosova, Irina Zhluktova, Daria Ruzhitskaya +6
Quantum key distribution systems offer cryptographic security, provided that all their components are thoroughly characterised. However, certain components might be vulnerable to a…
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…
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…
