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.

Laser Light to Cool Object to Quantum Ground State

For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the Vienna Center for Quantum Science and Technology (VCQ), have managed to cool a miniature mechanical object to its lowest possible energy state using laser light.

Quantum behavior with a flash

Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large, ‘macroscopic' object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales.
