Nonclassicality of a delayed remote-controlled quantum computing model
Peicun Lin, Dongyang Wang, Yong Liu +1
Delegated quantum computing is likely to become the primary means for most people to access quantum computers in the future. However, these hardware inevitably operate beyond clien…
Robustness of fiber-optic attenuators to 1061-nm sub-nanosecond pulsed laser radiation in quantum key distribution systems
Daria Ruzhitskaya, Irina Zhluktova, Anastasiya Ponosova +10
The security of quantum key distribution (QKD) systems relies on the physical integrity of their components. While laser-damage attacks (LDAs) using high-power continuous-wave (cw)…
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
