The recent developments in quantum optics transformed atom interferometry from pure fundamental research to a powerful technique giving birth to a multitude of tools for metrology, gravimetry and fundamental physics. Besides the measurement of fundamental constants (Fine structure constant, gravitational constants) or the tests of fundamental laws (Equivalence principle), the application of atom interferometers for gravimetry or generally for the measurement of inertial forces (Earth rotation, acceleration) became a central focus of research. Indeed, atom interferometers show not only a high sensitivity compared to other techniques but also an intrinsically high accuracy comparable to atomic clocks. Our efforts to advance the field of atom interferometry by carrying out challenging experiments, building networks and identifying the physical limitations as well as the potential applications will be reported in this contribution.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
