Tunable topological enhancement of covariant quantum Fisher information via non-Bloch skin effect in non-Hermitian SSH lattices
Qi-Cheng Wu, Yan-Hui Zhou, Tong Liu +2
The covariant quantum Fisher information (CQFI) has recently been established as the ultimate precision benchmark for pseudo-Hermitian sensors [Phys. Rev. Lett. 136, 080802 (2026)]…
Parameter trajectory engineering for state transfer and quantum sensing in non-Hermitian two-level systems
Qi-Cheng Wu, Yan-Hui Zhou, Biao-liang Ye +4
Exceptional points (EPs) in non-Hermitian systems give rise to enhanced sensitivity and chiral state transfer, which are important for quantum technologies. Although parameter traj…
Enhanced quantum sensing in time-modulated non-Hermitian systems
Qi-Cheng Wu, Yan-Hui Zhou, Tong Liu +3
Enhancing the sensitivity of quantum sensing near an exceptional point represents a significant phenomenon in non-Hermitian (NH) systems. However, the application of this property…
Shortcuts to adiabatic state transfer in time-modulated two-level non-Hermitian systems
Qi-Cheng Wu, Jun-Long Zhao, Yan-Hui Zhou +4
Nontrivial spectral properties of non-Hermitian systems can give rise to intriguing effects that lack counterparts in Hermitian systems. For instance, when dynamically varying syst…
-photon blockade with an -photon parametric drive
Yan-Hui Zhou, Fabrizio Minganti, Wei Qin +5
We propose a mechanism to engineer an -photon blockade in a nonlinear cavity with an -photon parametric drive . When an -photon-excitation reson…
