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…
Bell-Mermin-Klyshko Inequalities and One-way Information Deficit of Dirac Fields in Noninertial Frames
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
We investigate the Bell-Mermin-Klyshko inequalities and the one-way information deficit of Dirac fields in noninertial frames, where the quantum correlations are shared between ine…
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…
Entropic uncertainty relations and quantum Fisher information of top quarks in a large hadron collider
Biao-Liang Ye, Li-Yuan Xue, Zhi-Qiang Zhu +2
We employ the entropic uncertainty relations and the quantum Fisher information to explore the formation of quark pairs at a large hadron collider through the combinatio…
