光量子存储器

Optical quantum memory

A. I. Lvovsky, B. C. Sanders, W. Tittel

摘要:

量子存储器在许多方面对量子信息处理都很重要:它是一种同步设备,可以匹配量子计算机中的各种进程;它是一种身份量子门,可以保持任何状态不变;它是一种工具,可以将预先发出的光子转换为按需光子。除了量子计算,量子存储器将有助于使用量子中继器实现长距离量子通信。这个基本的量子门的重要性是由正在研究的众多光量子存储器机制来举例说明的:光延迟线、腔、电磁感应透明性、光子回波和非共振法拉第相互作用。在这里,我们报告了光量子存储器领域的最新技术,包括成功的量子存储器和当前性能水平的标准。

英文摘要:

Quantum memory is important to quantum information processing in many ways: a synchronization device to match various processes within a quantum computer, an identity quantum gate that leaves any state unchanged, and a tool to convert heralded photons to photons-on-demand. In addition to quantum computing, quantum memory would be instrumental for the implementation of long-distance quantum communication using quantum repeaters. The importance of this basic quantum gate is exemplified by the multitude of optical quantum memory mechanisms being studied: optical delay lines, cavities, electromagnetically-induced transparency, photon-echo, and off-resonant Faraday interaction. Here we report on the state-of-the-art in the field of optical quantum memory, including criteria for successful quantum memory and current performance levels.
