Quantum technologies with single atoms


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 by highly trained experts due to their size, complexity, and high cost.

In this project we develop compact, robust and simple experimental setups to manipulate single atoms and couple them to quantum networks. For example, we use micrometer-scale lenses that are 3D printed onto the tip of standard optical fibers. This makes these lenses suitable for trapping individual atoms, capturing their fluorescence with high efficiency and coupling this fluorescence into a fiber optical network.
