The goal of the group Applied Quantum Interactions (AQI) is the better understanding of quantum mechanical interactions in order to use them efficiently for applications.
The group is closely collaborating with the other groups of the Applied Quantum Systems department.
The AQI group is specialised in the investigation of colour centres in solids. Here, the nitrogen–vacancy (NV) centre in diamond is of particular interest.
Since the quantum mechanical state of an NV centre can be precisely manipulated, it can be used perfectly as a model system to explore quantum physical effects.
The focus of our group is to investigate the interaction between multiple NV centres as well as the interaction to other neighbouring electronic and nuclear spins.
For example, cross-relaxations between spins or Landau–Zener transitions in complex multi-level systems can be studied.
This knowledge can be used, among other things, for the generation of sensitive quantum sensors, for the optimisation of 'gates' in quantum computing, and for the preparation of non-thermodynamic states in magnetic resonance methods (NMR, EPR).
