Abstract

ABSTRACT Quantum memory (QM) enables quantum state mapping between flying and stationary quantum states and is the building block of quantum information science, which enables to achieve a plethora of quantum information protocols, such as quantum state transfer across remote quantum nodes, distributed quantum logic gate, and quantum precession measurement network. Great progresses of quantum memories have been achieved, and electromagnetically induced transparency (EIT) is one of the well-understood approaches of QM. Quantum states of light are the essential quantum resources for implementing quantum enhanced task, and thus it is a long-standing goal to store and release non-classical states of light. This paper presents an up-to-date review on recent developments in EIT-based QM: EIT quantum memories have been realized in warm atomic cell, cold atoms and solid system, respectively; and EIT mechanism has been applied to store and release single photon, squeezed state, entangled photon pairs and multipartite entangled states of optical modes.

非经典光态的电磁感应透明量子存储器

摘要量子存储器（QM）实现了飞行量子态和静止量子态之间的量子状态映射，是量子信息科学的基石，它能够实现大量量子信息协议，如跨远程量子节点的量子状态转移、分布式量子逻辑门和量子旋进测量网络。量子存储器已经取得了很大的进展，电磁感应透明（EIT）是QM的一种众所周知的方法。光的量子态是实现量子增强任务的重要量子资源，因此存储和释放光的非经典态是一个长期的目标。本文对基于EIT的QM的最新进展进行了综述：EIT量子存储器已分别在热原子电池、冷原子和固体系统中实现；EIT机制已被应用于存储和释放光学模式的单光子、压缩态、纠缠光子对和多部分纠缠态。图形摘要
