论文摘要
贵族天然气原子的核自旋与环境异常分离，可以在室温下保持其量子性能数小时。在这里，我们开发了一种通过使用相干的光输入来纠缠两个这样遥远的宏观集合的机制。每个集合中的光与贵族旋转之间的相互作用是通过与碱金属旋转的自旋交换碰撞介导的，碱性 - 金属旋转几乎是激发的。概述了使用 ^{3} \ text {he}或 ^{129} \ text {xe}实验实现的相关条件。
Nuclear spins of noble-gas atoms are exceptionally isolated from the environment and can maintain their quantum properties for hours at room temperature. Here we develop a mechanism for entangling two such distant macroscopic ensembles by using coherent light input. The interaction between the light and the noble-gas spins in each ensemble is mediated by spin-exchange collisions with alkali-metal spins, which are only virtually excited. The relevant conditions for experimental realizations with ^{3}\text{He} or ^{129}\text{Xe} are outlined.
