Abstract

A robust light storage and retrieval (LSR) in high dimensions is highly desirable for light and quantum information processing. However, most schemes on LSR realized up to now encounter problems due to not only dissipation, but also dispersion and diffraction, which make LSR with a very low fidelity. Here we propose a scheme to achieve a robust storage and retrieval of weak nonlinear high-dimensional light pulses in a coherent atomic gas via electromagnetically induced transparency. We show that it is available to produce stable (3 + 1)-dimensional light bullets and vortices, which have very attractive physical property and are suitable to obtain a robust LSR in high dimensions.

摘要

在光和量子信息处理中，高维的稳健光存储和检索（LSR）是非常理想的。然而，迄今为止实现的大多数 LSR 方案由于不仅存在耗散，还存在色散和衍射，因此其保真度非常低。在这里，我们提出了一种通过电磁感应透明来实现相干原子气体中弱非线性高维光脉冲的稳健存储和检索的方案。我们表明，通过这种方案可以产生稳定的（3+1）维光子弹和涡旋，它们具有非常吸引人的物理性质，适合在高维中获得稳健的 LSR。
