Quantum Fidelity Estimation in the Resource Theory of Nonstabilizerness
Zhiping Liu, Kun Wang, Xin Wang
Quantum fidelity estimation is essential for benchmarking quantum states and processes on noisy quantum devices. While stabilizer operations form the foundation of fault-tolerant q…
Mitigating Quantum Errors via Truncated Neumann Series
Kun Wang, Yu-Ao Chen, Xin Wang
Quantum gates and measurements on quantum hardware are inevitably subject to hardware imperfections that lead to quantum errors. Mitigating such unavoidable errors is crucial to ex…
Measurement Error Mitigation via Truncated Neumann Series
Kun Wang, Yu-Ao Chen, Xin Wang
Measurements on near-term quantum processors are inevitably subject to hardware imperfections that lead to readout errors. Mitigation of such unavoidable errors is crucial to bette…
Lower bound for the T count via unitary stabilizer nullity
Jiaqing Jiang, Xin Wang
We introduce magic measures to quantify the nonstabilizerness of multiqubit quantum gates and establish lower bounds on the count for fault-tolerant quantum computation. First,…
Physical Implementability of Linear Maps and Its Application in Error Mitigation
Jiaqing Jiang, Kun Wang, Xin Wang
Completely positive and trace-preserving maps characterize physically implementable quantum operations. On the other hand, general linear maps, such as positive but not completely…
