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…
Large Scale Entanglement Structure Detection in 100-Qubit Systems via Local Joint Measurements
Rui Li, Yuhang Wang, Chunxiao Du +5
Identifying the entanglement structure of a many-body quantum state, namely how its constituents partition into unentangled blocks, is a central task in quantum information science…
High-Order Exceptional Point-Based Rotation Sensing in Anti-Parity time Symmetric Microresonators
Wenxiu Li, Zelei Li, Jincheng Li +7
Exceptional points (EPs), which arise from non-Hermitian systems, have been extensively investigated for the development of high-performance gyroscopes. However, operating a non-He…
Squeezed-Light-Enhanced Dispersive Gyroscope based Optical Microcavities
Xiaoyang Chang, Wenxiu Li, Hao Zhang +3
Optical gyroscope based on the Sagnac effect have excellent potential in the application of high-sensitivity inertial rotation sensors. In this paper, we demonstrate that for an op…
Exceptional Point modulated by Kerr effect in Anti-Parity-Time Symmetry System
Tuoyu Chen, Zhisong Xiao, Shuo Jiang +6
With respect to parity-time (PT) symmetry, anti-parity-time (APT) symmetric system exhibits much easier readout mechanism due to its real frequency splitting. Generally, such syste…
Exceptional surface-enhanced Rotation Sensing with Robustness in an optical microcavity
Wenxiu Li, Yang Zhou, Peng Han +5
Exceptional points (EPs) are special singularities of non-Hermitian Hamiltonians. At an EP, two or more eigenvalues and the corresponding eigenstates coalesce. Recently, EP-based o…
High-sensitivity bio-sensor based on the real-splitting indirectly coupled Anti-Parity time symmetric WGMs
Wenxiu Li, Hao Zhang, Peng Han +5
Detecting the size of single nanoparticle with high precision is crucial to understanding the characteristic of the nanoparticle. In this paper, we research the single particle det…
Variable optical chirality in an atomic assisted microresonator
Hao Zhang, Wenxiu Li, Xiaoyang Chang +3
A whispering gallery mode resonator with a cavity-made slot filled atomic vapor is demonstrated, in which the chiral symmetry is broken induced by asymmetric backscattering of coun…
