Within the QI2-lab we primarily work on quantum metrology and sensing problems. We develop fundamental theory for quantum estimation tasks in order to focus on their optical implementations, with particular interest in atomic-ensemble and optomechanical quantum sensors. We also seek novel solutions in quantum information, cryptography and communication, especially exploring the device-independent framework.

We work on optimisation for and with the help of quantum computing. Examples: optimal compilation, variational algorithms, efficient embeddings.

We are a theoretical physics research group based at Trinity College Dublin. Our research interfaces open quantum systems, non-equilibrium statistical physics, and quantum information.
