Space-borne quantum test of the weak equivalence principle at the 10−17 level — •Sina Loriani, Sven Abend, Dennis Schlippert, Christian Schubert, Ernst Maria Rasel, and Naceur Gaaloul — Institut für Quantenoptik and Centre for Quantum Engineering and Space-Time Research (QUEST), Leibniz Universität Hannover, Welfengarten 1, D- 30167 Hannover, Germany
Matter wave interferometry provides a unique access to the interface of quantum theory and gravity and is well suited for probing various aspects of general relativity, ranging from its postulates as the equivalence principle to its implications such as gravitational waves. In this contribution, we present a dedicated satellite mission for testing the universality of free fall to 10−17 as proposed for the ESA Voyage 2050 initiative. The theoretical advances and technological maturity that would allow reaching this performance will be highlighted.
