Enhancing delocalization and entanglement in asymmetric discrete-time quantum walks
Hao Zhao, Qiyan He, Fengzhi Yang +8
In this paper, we investigate the enhancement of delocalization and coin-position entanglement in asymmetric discrete-time quantum walks (DTQWs). The asymmetry results from asymmet…

Maximal coin-position entanglement and non-Hermitian skin effect in discrete-time quantum walks
Ding Cheng, Yi Li, Hao Zhao +6
A distinctive feature of non-Hermitian systems is the skin effect, which has attracted widespread attention in recent studies. Quantum walks provide a powerful platform for explori…
