Our research on the theory of quantum nanostructures is motivated by the prospect of next generation quantum technologies for energy, sensing, and information processing.

Exploring the interface of condensed matter physics, quantum optics, -information, and -biology, we utilise cutting-edge analytical and numerical techniques to study the rich and complex quantum properties of engineered and natural nanostructures (such as for example semiconductor quantum dots, NV- centres in diamond, molecular systems). We are particularly interested in how these systems can be controlled and harnessed for practical applications and novel quantum technologies. Much of our work is performed in close collaboration with experimental colleagues.

Erik Gauger has joined IPaQS in January 2015 as a Royal Society of Edinburgh / Scottish Government Personal Research Fellow and Assistant Professor at Heriot-Watt University. Previously he received a Diplom degree in physics from the University of Konstanz (2005) before taking up a Marie Curie Early Stage Research Training Fellowship to obtain a DPhil from the University of Oxford (2009). Following a postdoctoral appointment at Oxford (2009-2011), Erik held appointments as Research Fellow and Senior Research Fellow at the Centre for Quantum Technologies, National University of Singapore (2011-2014).
