标题： Quantum hologram of macroscopically entangled light via the mechanism of diffuse light storage

摘要： 在本文中，我们考虑了一种量子存储方案，用于光在空间无序原子气体中散射传播。 信号光脉冲的散射捕获可以自然地与受激拉曼转换机制结合，形成一种长寿命的自旋相干。 然后，光的量子态可以映射到无序原子自旋子系统中，并在其内存储相对较长时间。 所提出的存储方案可用于存储$\Psi^{(-)}$贝尔态的宏观类比以及制备的纠缠原子态执行其量子全息图，这表明进一步的量子信息处理的可能性。 显示英文摘要

摘要： In the present paper we consider a quantum memory scheme for light diffusely propagating through a spatially disordered atomic gas. The diffuse trapping of the signal light pulse can be naturally integrated with the mechanism of stimulated Raman conversion into a long-lived spin coherence. Then the quantum state of the light can be mapped onto the disordered atomic spin subsystem and can be stored in it for a relatively long time. The proposed memory scheme can be applicable for storage of the macroscopic analog of the $\Psi^{(-)}$ Bell state and the prepared entangled atomic state performs its quantum hologram, which suggests the possibility of further quantum information processing.
