Clifford Perturbation Approximation for Quantum Error Mitigation
Ruiqi Zhang, Yuguo Shao, Fuchuan Wei +3
Quantum error mitigation (QEM) is critical for harnessing the potential of near-term quantum devices. Particularly, QEM protocols can be designed based on machine learning, where t…
Variational Graphical Quantum Error Correction Codes
Yuguo Shao, Yong-Chang Li, Fuchuan Wei +5
Quantum error correction is essential for achieving fault-tolerant quantum computation. However, most typical quantum error-correcting codes are designed for generic noise models,…
Detecting unfaithful entanglement by multiple fidelities
Ruiqi Zhang, Zhaohui Wei
Certifying entanglement for unknown quantum states experimentally is a fundamental problem in quantum computing and quantum physics. Because of being easy to implement, a most popu…
The sudden death of quantum advantage in correlation generations
Weixiao Sun, Fuchuan Wei, Yuguo Shao +1
As quantum error corrections still cannot be realized physically, quantum noise is the most profound obstacle to the implementations of large-scale quantum algorithms or quantum sc…
