Our group conducts research on the interface between quantum physics and gravity at the ÖAW institute IQOQI Vienna and the University of Vienna. Our vision is to test the quantum nature of gravity – by taking gravity and quantum experiments to where they have never been before.

“How does a quantum object gravitate?”, “How far can we push massive objects into the quantum regime?”, “How well can we measure gravity of microscopic systems?”. Such questions and their implications for the foundations of physics are the driving force behind our research. To address them we are developing quantum measurement and control techniques to investigate and utilize quantum states of motion of massive solid state objects. We are also developing inertial precision sensing techniques to measure the gravitational field of the smallest possible source masses. Our research aims to provide new insights on macroscopic quantum physics, on gravity at small scales and, in the long run, on the phenomenology of the gravity-quantum interface in table-top experiments.
