Scale-free localization in pseudo-Hermitian quantum walk
Haiting Zhang, Lei Xiao, Cui-Xian Guo +2
Scale-free localization is a distinctive phenomenon in non-Hermitian systems, where specific eigenstates, known as scale-free localized states (LSs), possess localization lengths t…
Non-Hermitian-enhanced quantum sensing in an optical interferometer
X. J. Huang, Lei Xiao, Bingzi Huo +2
The precision of quantum parameter estimation is traditionally constrained by the quantum Cramér-Rao bound, which is based on the Hermitian measurement framework. Recent studies of…
Chiral Entangled-State Generation through Dissipative Quantum Dynamics
Huixia Gao, Konghao Sun, Yiwen Han +6
Dissipation, though often detrimental to quantum entanglement, can be manipulated for the preparation of entangled states, wherein ingeniously designed quantum jump processes drive…
Experimental Observation of Dynamical Phase Transitions in a Dephased Photonic Quantum Walk
Xiaojian Huang, Lei Xiao, Bingzi Huo +3
Dynamical phase transitions in open quantum systems govern how non-equilibrium states relax toward a stationary state. We study these transitions experimentally using a discrete-ti…
Observation of Restored Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Xiaowei Wang, Ievgen I. Arkhipov, Quan Lin +5
Exceptional points (EPs) have attracted extensive research interest due to their intriguing properties. One of the hallmarks of EP physics is that dynamically encircling the EPs in…
Topological Sensing in the Dynamics of Quantum Walks with Defects
Xiaowei Tong, Xingze Qiu, Xiang Zhan +4
Topological quantum sensing leverages unique topological features to suppress noise and improve the precision of parameter estimation, emerging as a promising tool in both fundamen…
