论文摘要
我们在使用热原子蒸气来构建复杂量子物质的“自下而上”方法中证明了一种关键成分。我们在无激光冷却的情况下孤立和跟踪非常缓慢地移动单个原子。被动过滤使我们能够仔细选择其三维速度向量的原子的幅度低于$ \ bar {v}/20 $，其中$ \ bar {v} $是整体的平均速度。使用一种新型的光子相关技术，我们可以遵循单个$25μ$ M的视野内，以$>1μ$ s的速度慢慢移动原子的三维轨迹，没有明显的限制，同时观察了这些单个发射器的Rabi振荡。我们的结果证明了通过自下而上的方法应用热集合在量子记忆，成像和其他量子信息应用中利用的功率和可伸缩性。
We demonstrate a key ingredient in a 'bottom-up' approach to building complex quantum matter using thermal atomic vapors. We have isolated and tracked very slowly moving individual atoms without the aid of laser cooling. Passive filtering enabled us to carefully select atoms whose three-dimensional velocity vector has a magnitude below $\bar{v}/20$, where $\bar{v}$ is the mean velocity of the ensemble. Using a novel photon correlation technique, we could follow the three-dimensional trajectory of single, slowly moving atoms for $> 1μ$s within a $25μ$m field of view, with no obvious limit to the tracking ability while simultaneously observing Rabi oscillations of these single emitters. Our results demonstrate the power and scalability of thermal ensembles for utilization in quantum memories, imaging, and other quantum information applications through bottom-up approaches.
