The projects and published results in this group deal with quantum control of spin networks.

We investigate robust quantum control of spin networks, specifically focused on energy landscape control, using a range of optimisation and control approaches from gradient-based optimisation to reinforcement learning. We also study approaches to describe and characterise the network dynamics and process tomography techniques.
