摘要

我们通过使用一系列液晶器件(“g板”)获得的光子实现来模拟一维强制量子行走，这些器件对光束中的光子施加偏振相关的横向踢。我们观察到局部初始状态的重聚焦现象。

Refocusing in forced photonic quantum walks controlled by liquid crystal gratings

We mimic one dimensional forced quantum walks by using the photonic implementation obtained by means of a sequence of liquid-crystal devices (”g-plates”), which apply polarization-dependent transverse kicks to the photons in the beam. We observed refocusing phenomena for localized initial states.
