Nondemolition filtering of an embedded cluster-state scar under continuous local monitoring
Ximo Wang, Xi Zhao, Xiayu Sun +6
Identifying a low-entanglement eigenstate inside a many-body spectrum and preserving it during measurement are distinct tasks. We construct an explicit local ring Hamiltonian with…
Sparse and weak-measurement certification of graph-edge entanglement in PXP scar wavepackets
Ximo Wang, Yichi Zhang, Qiwei Han +6
An imperfect many-body revival does not by itself certify the entanglement of the returning state. We give a finite-record protocol for graph-edge localizable entanglement along sc…
Full Inseparability and Genuine Multipartite Entanglement Coincide for Finite-Mode Gaussian States
Yu Yang, Yuhang Wang, Chunxiao Du +6
For general mixed states, entanglement across every bipartition need not imply genuine multipartite entanglement (GME), because a biseparable decomposition may switch the separable…
