Identification of quantum generative circuits with parallel quantum neural network
Zheping Wu, Xiaopeng Huang, Hengyue Jia +2
The rapid emergence of quantum technology has raised new challenges in distinguishing various quantum circuits of similar functions. In this work, we propose parallel quantum embed…
Practical security of local local oscillator continuous-variable quantum key distribution systems with pulse width mismatch
Yi Zheng, Jiarui Wu, Chenlei Fang +3
In continuous-variable quantum key distribution (CVQKD) systems, using a local local oscillator (LLO) scheme removes the local oscillator side channel, enhances Bob's detection per…
Self-attention U-Net decoder for toric codes
Wei-Wei Zhang, Zhuo Xia, Wei Zhao +2
In the NISQ era, one of the most important bottlenecks for the realization of universal quantum computation is error correction. Stabiliser code is the most recognizable type of qu…
Quantum versatility in PageRank
Wei-Wei Zhang, Zheping Wu, Hengyue Jia +4
Quantum mechanics empowers the emergence of quantum advantages in various fields, including quantum algorithms. Quantum PageRank is a promising tool for a future quantum internet.…
Quantum hacking: Induced-photorefraction attack on a practical continuous-variable quantum key distribution system
Yiliang Wang, Yi Zheng, Chenlei Fang +2
We explore a new security loophole in a practical continuous-variable quantum key distribution (CVQKD) system, which is opened by the photorefractive effect of lithium niobate-base…
