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)]…
Observation of Non-Markovian Evolution of Tripartite Quantum Steering
Yan Wang, Shao-qi Lin, Rui-qi Shen +6
The memory effects in open quantum systems can induce information backflow and revive quantum correlations, thereby providing a powerful way to protect and recover useful quantum r…
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…
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…
Quantum voting machine encoded with microwave photons
Yu Zhang, Chuiping Yang, Qiping Su +4
We propose a simple quantum voting machine using microwave photon qubit encoding, based on a setup comprising multiple microwave cavities and a coupled superconducting flux qutrit.…
