The trapping of single atoms in optical dipole traps is widely used in experiments on the implementation of quantum processors based on neutral atoms, and studying interatomic interactions. Typically, such experiments employ lenses with a large numerical aperture (NA > 0.5), highly sensitive EMCCD cameras, or photon counters. In this work, we demonstrate trapping and detection of single rubidium atoms using a long-focus objective lens with a numerical aperture NA = 0.172 and a FLir Tau CNV sCMOS camera.

使用远摄镜头捕获和检测光偶极陷阱中的单个铷原子

光偶极阱中单个原子的俘获被广泛用于基于中性原子的量子处理器实现的实验，以及研究原子间相互作用。通常，此类实验采用具有大数值孔径 (NA > 0.5) 的镜头、高灵敏度 EMCCD 相机或光子计数器。在这项工作中，我们展示了使用数值孔径 NA = 0.172 的长焦物镜和 FLir Tau CNV sCMOS 相机捕获和检测单个铷原子。
