In recent years, matter wave interferometry has developed into a powerful tool for the ultra precise measurement of accelerations and rotations. It is used in various laboratories for experiments in the fields of fundamental physics and metrology.

FINAQS (Future Inertial Atomic Quantum Sensors), a collaboration of five European research groups, aims at developing new atomic quantum sensors based on coherent and brilliant atomic sources. For this purpose, we will implement new atom optics concepts, particularly the first gravimeter and quantum gyroscope using degenerate quantum gases. Another goal of FINAQS is extending the usefulness of atom interferometers to include practical applications, such as on-site high precision measurements of local gravity, which will benefit research in geology and seismology, amongst others. Each FINAQS partner will contribute its experience and designs to the development of the project.

We will present an overview of the key technologies that will be developed or adapted from previous laboratory based experiments for the realization of two mobile and yet precise FINAQS quantum sensors.
