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…
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…
