Mathieu Control of the Effective Coupling in Superconducting Qubits
Yi-Han Yu, Xin-Yi Li, Kai Xu +1
A common challenge in superconducting quantum circuits is the trade-off between strong coupling and computational subspace integrity. We present Mathieu control, which uses a non-r…
Tomography-assisted noisy quantum circuit simulator using matrix product density operators
Wei-guo Ma, Yun-Hao Shi, Kai Xu +1
In recent years, efficient quantum circuit simulations incorporating ideal noise assumptions have relied on tensor network simulators, particularly leveraging the matrix product de…
Distributed Quantum Computation via Entanglement Forging and Teleportation
Tian-Ren Jin, Kai Xu, Heng Fan
Distributed quantum computation is a practical method for large-scale quantum computation on quantum processors with limited size. It can be realized by direct quantum channels in…
Noisy Probabilistic Error Cancellation and Generalized Physical Implementability
Tian-Ren Jin, Kai Xu, Yu-Ran Zhang +1
Decoherence severely limits the performance of quantum processors, posing challenges to reliable quantum computation. Probabilistic error cancellation, a quantum error mitigation m…
Dynamics of quantum coherence in many-body localized systems
Jin-Jun Chen, Kai Xu, Li-Hang Ren +2
We demonstrate that the dynamics of quantum coherence serves as an effective probe for identifying dephasing, which is a distinctive signature of many-body localization (MBL). Quan…
Recovery of damaged information via scrambling in indefinite casual order
Tian-Ren Jin, Tian-Ming Li, Zheng-An Wang +3
Scrambling prevents the access to local information with local operators and therefore can be used to protect quantum information from damage caused by local perturbations. Even th…
Purity-Assisted Zero-Noise Extrapolation for Quantum Error Mitigation
Tian-Ren Jin, Yun-Hao Shi, Zheng-An Wang +3
Quantum error mitigation aims to reduce errors in quantum systems and improve accuracy. Zero-noise extrapolation (ZNE) is a commonly used method, where noise is amplified, and the…
