长期以来，单粒子水平上的光与物质相互作用的研究被认为纯粹是学术性的。如今，全新的应用即将出现，特别是在光学领域。新的光力被发现，使人们能够将原子存储很长时间，以至于仅用一个原子就可以实现真正的量子协议。第一个例子涉及实现单光子源及其性能的实时控制。这种单光子服务器传递的光子比特流在量子信息科学中非常有用。第二个实验涉及单个原子与飞行光子的确定性纠缠。随后将原子态映射到第二个光子上，使得根据需要产生纠缠光子成为可能。这种新颖方案的实验演示是朝着产生高度纠缠的多光子量子态和原子腔系统的可扩展量子网络迈出的重要一步。文章不可用。
For a long time, the investigation of light-matter interaction at the single-particle level was considered purely academic. Today, fundamentally new applications are on the horizon, in particular in the optical domain. New light forces have been discovered, enabling one to store atoms for such a long time that genuine quantum protocols can be realized with just one single atom. The first example concerns the realization of a source of single photons with realtime control of its performance. The bit stream of photons delivered by such a single-photon server is useful in quantum information science. A second experiment concerns the deterministic entanglement of a single atom with a flying photon. Subsequent mapping of the atomic state onto a second photon makes possible to produce entangled photons on demand. The experimental demonstration of such a novel scheme is an important step towards the production of highly entangled many-photon quantum states and scalable quantum networks of atom-cavity systems.
