The application of cold and ultracold atoms in light-pulse atom interferometry enables the development of new technologies, including inertial measurement systems for navigation. Quantum sensors utilizing atom interferometry offer precise measurements of inertial forces with a focus on long-term stability, yet developing sensors for field applications requires advancements in the development of compact and scalable technology.

One of our goals is the development of new electronics that control the sensor's operation. In the past, these have often been built using analog components only. Especially in the feedback loops controlling the laser frequency, digital components offer more flexibility in adjusting operational parameters. This poster presents an overview of our proposed quantum sensor, highlighting new developments for laser stabilization, partially based on the ARTIQ experiment control framework.
