相干原子气体中（3+1）维弱光子弹和涡旋的存储和检索
Storage and retrieval of (3+1)-dimensional weak-light bullets and vortices in a coherent atomic gas
摘要：
在光和量子信息处理中，高度期望在高维度中鲁棒的光存储和检索（LSR）。然而，目前实现的大部分LSR方案不仅存在耗散问题，还存在色散和衍射问题，使得LSR的保真度很低。在这里，我们提出了一个方案，以实现一个强大的存储和检索弱非线性高维光脉冲在相干原子气体通过电磁诱导透明。我们证明了它可以产生稳定的（3+1）维光子弹和涡旋，它们具有非常吸引人的物理性质，适合于在高维中获得鲁棒的LSR。
英文摘要：
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.
