Quantum Control

Utilising the full potential of quantum physics for practical quantum technologies requires control. We are investigating novel control strategies and algorithms, not just to stabilise the dynamics of a system, but to design a system operating efficiently and robustly. This is often linked to system identification and learning techniques.
