论文摘要
单个超低原子的捕获是从量子计算和通信到传感的应用的重要工具。但是，大多数实验设置虽然非常精确且通用，但由于其尺寸较大，复杂性和高成本，才能在专门的实验室环境中进行操作。在这里，我们在光学镊子中介绍了一个新的诱捕概念，该概念是基于千分尺尺度镜片的3D印刷在标准光纤尖端上的。这些镜头的独特特性使它们适合于捕获单个原子并以高效率捕获其荧光。在探索性实验中，我们建立了结构的真空兼容性和鲁棒性，并成功形成了一个磁光陷阱，以实现其附近的超电原子。这使它们成为便携式原子量子设备的有希望的组件。
Trapping of single ultracold atoms is an important tool for applications ranging from quantum computation and communication to sensing. However, most experimental setups, while very precise and versatile, can only be operated in specialized laboratory environments due to their large size, complexity and high cost. Here, we introduce a new trapping concept for ultracold atoms in optical tweezers based on micrometer-scale lenses that are 3D printed onto the tip of standard optical fibers. The unique properties of these lenses make them suitable for both trapping individual atoms and capturing their fluorescence with high efficiency. In an exploratory experiment, we have established the vacuum compatibility and robustness of the structures, and successfully formed a magneto-optical trap for ultracold atoms in their immediate vicinity. This makes them promising components for portable atomic quantum devices.
