Atom interferometry based quantum inertial navigation sensor — •Mouine Abidi, Philipp Barbey, Xingrun Chen, Ann Sabu, Matthias Gersemann, Dennis Schlippert, Ernst. M. Rasel, and Sven Abend — Leibniz Universität Hannover - Institut für Quantenoptik, Hannover, Germany

Current GNSS-based navigation systems and MEMS sensors provide convenient capabilities but are constrained by GNSS signal unavailability, vulnerability to jamming, and the long-term drift of MEMS sensors. In contrast, atom interferometry-based inertial sensors offer exceptional sensitivity and drift-free performance, making them ideal for applications in navigation, geodesy, and fundamental physics.

In this talk, the latest advancements from the QGyro project will be presented, focusing on the development of a quantum accelerometer that integrates state-of-the-art technologies, including a fiber-based laser system, flat-top beam shaping, ARTIQ electronics, and compact vacuum technology.

We also demonstrate the integration of this compact and robust quantum accelerometer onto a gimbal platform, facilitating its hybridization with classical MEMS sensors and quantum inertial navigation devices, such as accelerometers and gyroscopes. This hybrid system provides continuous, stable, and highly sensitive measurements of accelerations and rotations.

This work is supported by the Federal Ministry of Economics and Climate Protection (BMWK) due to the enactment of the German Bundestag under Grant No. DLR 50NA2106 (QGyro+).
