The main research objective of our group is to investigate quantum effects of nano- and microscale systems and their implications for the foundations and applications of quantum physics. Our goal is to gain access to a completely new parameter regime for experimental physics with respect to both size and complexity.

Bringing bonded mirrors out of the laboratory and into the light

Quantum physicists at the University of Vienna present yet another example that fundamental research can create unexpected technological innovations. The start-up “Crystalline Mirror Solutions,” or CMS, is focused on the manufacturing of high-performance mirrors for optical precision measurement.

Cooling by measurement

Observing a physical quantity without disturbing it is a key capability for the control of individual quantum systems. Such back-action-evading or quantum non-demolition measurements were first introduced in the 1970s for gravitational wave detection, and now such techniques are an indispensable tool throughout quantum science.
