In light pulse atom interferometry, ultracold atoms open the prospect of developing new techniques and concepts, in particular to increase the sensitivity of inertial measurements.

The possibility of precise motion control combined with large momentum transfer through double Bragg diffraction and Bloch oscillations contributed to the development of a new concept to create two simultaneous interferometers from a single BEC, as employed for the differentiation between rotations and accelerations. Thanks to the symmetry of this geometry, its extension can form the basis for a compact six-axis quantum inertial measurement unit based on atom-chip technology.

The underlying concepts, the system design used for this purpose, and the technical realization are presented in this contribution.
