快速发展的量子原子光学领域的一个重要方面是在比平均场近似更深的层次上探索超冷原子的行为，其中单个原子的量子特性变得重要。随着可靠的单原子源的创建和检测，最近取得了重大进展，这是测试基本量子过程的关键工具。在这里，我们创建了一个源组成的一个单一的超冷亚稳态氦原子，这使得新的自由空间量子原子光学实验与大的德布罗意布罗意波长的单个大质量粒子进行。
An important aspect of the rapidly growing field of quantum atom optics is exploring the behavior of ultracold atoms at a deeper level than the mean field approximation, where the quantum properties of individual atoms becomes important. Major recent advances have been achieved with the creation and detection of reliable single-atom sources, which is a crucial tool for testing fundamental quantum processes. Here, we create a source comprised of a single ultracold metastable helium atom, which enables novel free-space quantum atom optics experiments to be performed with single massive particles with large de Broglie wavelengths.
