Single particle-resolved fluorescence imaging is an enabling technology in cold-atom physics. However, so far, this technique has not been available for nanophotonic atom-light interfaces. Here, we image single atoms that are trapped and optically interfaced using an optical nanofiber. Near-resonant light is scattered off the atoms and imaged while counteracting heating mechanisms via degenerate Raman cooling. We detect trapped atoms within 150 ms and record image sequences of given atoms. Building on our technique, we perform two experiments which are conditioned on the number and position of the nanofiber-trapped atoms. We measure the transmission of nanofiber-guided resonant light and verify its exponential scaling in the few-atom limit, in accordance with Beer-Lambert’s law. Moreover, depending on the interatomic distance, we observe interference of the fields that two simultaneously trapped atoms emit into the nanofiber. The demonstrated technique enables postselection and possible feedback schemes and thereby opens the road toward a new generation of experiments in quantum nanophotonics.

成像和定位与纳米光子波导接口的单个原子。

单粒子分辨荧光成像是冷原子物理学中的一项使能技术。然而，到目前为止，该技术还不适用于纳米光子原子-光界面。在这里，我们成像的单个原子被捕获并使用光学纳米纤维光学连接。近共振光从原子上散射并成像，同时通过退化的拉曼冷却抵消了加热机制。我们在150毫秒内检测到被捕获的原子，并记录给定原子的图像序列。以我们的技术为基础，我们进行了两个实验，这些实验以被纳米纤维捕获的原子的数量和位置为条件。根据比尔-兰伯特定律，我们测量纳米纤维引导的共振光的透射率，并在少数原子极限内验证其指数尺度。而且，根据原子间距离我们观察到两个同时捕获的原子发射到纳米纤维中的场的干扰。所展示的技术使后选择和可能的反馈方案成为可能，从而为量子纳米光子学中的新一代实验开辟了道路。
