The Cluster of Excellence QUEST (Centre for Quantum Engineering and Space-Time Research) started to work in November 2007 at the host institution Leibniz Universität Hannover (LUH) and at four partner institutions: Physikalisch-Technische Bundesanstalt (PTB), Max-Planck-Institut für Gravitationsphysik (MPI), Laser Zentrum Hannover (LZH) and Zentrum für angewandte Raumfahrttechnologie und Mikrogravitation (ZARM). Within QUEST new technologies and fundamental theoretic works are being developed in four main areas of research: Quantum Engineering, Quantum Sensors, Space-Time Physics and Enabling Technologies. The new ideas of quantum engineering could enable reaching unprecedented levels of precision in metrology as well as testing fundamental physical laws. QUEST is being funded for 5 years within the Excellence Initiative of the Deutsche Forschungsgemeinschaft (DFG).
The Institute for Experimental Quantum Metrology was established within a joint appointment between the Leibniz Universität Hannover (LUH) and the Physikalisch-Technische Bundesanstalt (PTB) on the premises of PTB. The head of the Institute, Prof. Dr. Piet Schmidt, is a professor at the LUH. The institutes hosts three research groups: Multi-Ion Clocks, led by Dr. Tanja Mehlstäubler, Trapped-Ion Quantum Engineering, led by Prof. Dr. Christian Ospelkaus, and Quantum Logic Spectroscopy, led by Prof. Dr. Piet Schmidt.
