Quantum networking with atomic ensembles

这项实验研究计划将探索与原子合奏量子网络。本研究将在强耦合的情况下探索原子系综-光系统。先前研究的腔QED系统依赖于非常高精细度的腔来实现单原子和单光子之间的如此强的原子-场耦合。与先前的工作不同，这项新工作将使用由光学厚原子系综提供的原子-光子相互作用的集体增强。特别是，该团队提出通过使用原子系综和线性光学的协同作用来实现双节点量子网络。该计划的更广泛影响涉及教育以及量子通信的应用。

This experimental research program will explore quantum networking with atomic ensembles. The research will exploit atomic ensemble-light system in the regime of strong coupling. Previously studied cavity QED systems relied on very high-finesse cavities to achieve such strong atom-field coupling between a single atom and a single photon. Unlike this prior work, this new work will use collective enhancement of atom-photon interaction, provided by optically thick atomic ensembles. Particularly, the team proposes to realize a two-node quantum network by using a synergy of atomic ensembles and linear optics. The broader impact of the program involves education as well as applications to quantum communication.
