论文摘要
存储和保留光子量子状态的光学量子记忆依赖于光子状态在光学上可访问的物质状态的连贯映射。在这里,我们概述并表征方案,以将光子的状态映射到长期寿命但可获得的贵族气体旋转的集体状态。该映射采用与碱蒸气随机碰撞引起的连贯的自旋交流相互作用。我们提出了两个操作方案中有效的存储策略,并分析其绩效,以进行几种提出的实验配置。
Optical quantum memories, which store and preserve the quantum state of photons, rely on a coherent mapping of the photonic state onto matter states that are optically accessible. Here we outline and characterize schemes to map the state of photons onto long-lived but optically-inaccessible collective states of noble-gas spins. The mapping employs coherent spin-exchange interaction arising from random collisions with alkali vapor. We propose efficient storage strategies in two operating regimes and analyze their performance for several proposed experimental configurations.
