Bottom-up approach to room temperature quantum systems
Abstract
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 , where 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 s within a 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.
