Temporal modulation as a resource: enhanced frequency estimation in continuous variable systems
Ningxin Kong, Qiongyi He, Matteo G. A. Paris
Frequency estimation, a cornerstone of quantum metrology, has been significantly enhanced by advanced quantum sensing strategies. However, most protocols rely either on static or t…
Enhanced quantum metrology by criticality-assisted noncommutative preparation
Ningxin Kong, Matteo G. A. Paris, Qiongyi He
Quantum criticality is a resource for quantum-enhanced metrology, but existing schemes face intrinsic limitations. These arise because using criticality directly in the encoding dy…
Non-commutativity as a Universal Characterization for Enhanced Quantum Metrology
Ningxin Kong, Haojie Wang, Mingsheng Tian +4
A central challenge in quantum metrology is to effectively harness quantum resources to surpass classical precision bounds. Although recent studies suggest that the indefinite caus…
Exceptional-Point-Induced Nonequilibrium Entanglement Dynamics in Bosonic Networks
Chenghe Yu, Mingsheng Tian, Ningxin Kong +3
Exceptional points (EPs), arising in non-Hermitian systems, have garnered significant attention in recent years, enabling advancements in sensing, wave manipulation, and mode selec…
Manipulating Spectral Windings and Skin Modes through Nonconservative Couplings
Ningxin Kong, Chenghe Yu, Yilun Xu +3
The discovery of the non-Hermitian skin effect (NHSE) has revolutionized our understanding of wave propagation in non-Hermitian systems, highlighting unexpected localization effect…
