Versatile Control of Nonlinear Topological States in Non-Hermitian Systems

Zhao-Fan Cai, Yu-Chun Wang, Yu-Ran Zhang +2

The non-Hermitian skin effect (NHSE) and nonlinearity can both delocalize topological modes (TMs) from the interface. However, the NHSE requires precise parameter tuning, while non…

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…

High-order topological pumping on a superconducting quantum processor

Cheng-Lin Deng, Yu Liu, Yu-Ran Zhang +21

High-order topological phases of matter refer to the systems of -dimensional bulk with the topology of -th order, exhibiting -dimensional boundary modes and can be cha…

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…

Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor

Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24

Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
