Hybrid quantum inertial sensors based on cold atom interferometry have been proposed as a more accurate alternative for tracking acceleration, e.g. for inertial navigation, compared to current classical accelerometers. In such hybrid sensors, the atom interferometer is used to correct the drift of the classical sensor. Furthermore, the hybridization of both sensors allows for a higher repetition rate and dynamic range compared to pure quantum atom interferometers. In this project, we plan to build a combination of an atom interferometer based on stimulated Raman transitions in a Mach-Zehnder configuration using Rubidium-87 with opto-mechanical sensors, where the acceleration is measured sequentially for each axis. In the framework of this project a simulation tool was developed to find the optimal operating parameters.
This poster will give an overview of the current design and of the simulations that were used to optimize the measurement sequence. Further, an outlook is given on future on-site measurements and intermediate goals of the project.
