Vulnerability of fault-tolerant topological quantum error correction to quantum deviations in code space
Yuanchen Zhao, Dong E. Liu
Quantum computers face significant challenges from quantum deviations or coherent noise, particularly during gate operations, which pose a complex threat to the efficacy of quantum…
Information scrambling and entanglement in quantum approximate optimization algorithm circuits
Chen Qian, Wei-Feng Zhuang, Rui-Cheng Guo +2
Variational quantum algorithms, which consist of optimal parameterized quantum circuits, are promising for demonstrating quantum advantages in the noisy intermediate-scale quantum…
Noise-resilient phase estimation with randomized compiling
Yanwu Gu, Yunheng Ma, Nicolo Forcellini +1
We develop an error mitigation method for the control-free phase estimation. We prove a theorem that under the first-order correction, the noise channels with only Hermitian Kraus…
Attacking practical quantum key distribution system with wavelength dependent beam splitter and multi-wavelength sources
Hong-Wei Li, Shuang Wang, Jing-Zheng Huang +9
Unconditional security of quantum key distribution protocol can be guaranteed by the basic property of quantum mechanics. Unfortunately, the practical quantum key distribution syst…
Field Experiment on a Robust Hierarchical Metropolitan Quantum Cryptography Network
Fangxing Xu, Wei Chen, Shuang Wang +9
A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node…
