KOAQS-II

Compact Atomic Source for Quantum Sensors

Laser-cooled, neutral atoms are a central basis of many quantum technologies – for example, for portable atomic clocks or atom interferometers. Their use requires reliable atomic sources that are easy to operate, compact and robust. Until now, these have often been individual laboratory setups that require specialized expertise.

The QVLS-iLabs project KOAQS-II aims to provide a turnkey atomic source that can be operated without expert knowledge and offers standardized interfaces. The developed solution is intended to be used both in research and in industrial applications and to enable cost-effective and scalable manufacturing.

Building on the successful results of the first project phase, the system is being further miniaturized and mechanically optimized. New microstructured atom ovens and a modular design enable a compact form factor and the use of different types of atoms – from alkali atoms to ytterbium and strontium for optical atomic clocks. The goal is to demonstrate practical, robust atomic sources as a key component of future quantum systems.
