Our research combines the development of new quantum technologies with fundamental quantum experiments. The main activities of the group include quantum optical control of solid-state nano- and micro-mechanical devices, the exploration of their quantum properties for fundamental questions and novel applications, as well as micro-mechanical measurements of weak gravitational forces.
