光量子存储器存储和保存光子的量子态，依赖于光子态到可光学访问的物质态的相干映射。在这里，我们概述并描述了将光子状态映射到长期存在但光学上无法访问的惰性气体自旋集体状态的方案。该映射采用了与碱蒸气随机碰撞产生的相干自旋交换相互作用。我们提出了两种操作模式下的高效存储策略，并分析了它们在几种提议的实验配置下的性能
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
