Generalized Entanglement of Purification Criteria for 2-Producible States in Multipartite Systems
Tian-Ren Jin, Yu-Ran Zhang, Heng Fan
Multipartite entanglement has a much more complex structure than bipartite entanglement. A state that lacks generic multipartite entanglement is 2-producible, i.e. it can be writte…
Characterizing Many-body Dynamics with Projected Ensembles on a Superconducting Quantum Processor
Zhiguang Yan, Zi-Yong Ge, Rui Li +3
Quantum simulators offer a new opportunity for the experimental exploration of non-equilibrium quantum many-body dynamics, which have traditionally been characterized through expec…
Non-Hermitian sensing from the perspective of post-selected measurements
Neng Zeng, Tao Liu, Keyu Xia +2
By employing the Naimark dilation, we establish a fundamental connection between non-Hermitian quantum sensing and post-selected measurements. The sensitivity of non-Hermitian quan…
Prethermalization by Random Multipolar Driving on a 78-Qubit Superconducting Processor
Zheng-He Liu, Yu Liu, Gui-Han Liang +43
Time-dependent drives hold the promise of realizing non-equilibrium many-body phenomena that are absent in undriven systems. Yet, drive-induced heating normally destabilizes the sy…
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…
