Better quantum devices
Building practical quantum technologies is hard. We develop new approaches to quantum devices and physics, including superconducting qubits and devices that break time-reversal symmetry to bring quantum technologies to reality. Applications for such systems include high precision sensing, quantum simulators and photosynthesis. If you are an exceptional student looking to study for your Honours, Masters or PhD at the cutting edge of physics and technology, then please get in touch.

Quantum error correction
Quantum processors will suffer from errors arising from noise. This problem can be fixed using error correcting codes, which redundantly encode quantum information in a way that enables its recovery in the event that errors occur. How do we make and implement better codes in quantum systems? We take inspiration from information theory and other areas of quantum physics, including cosmology, to design codes that are resilient against noise. Please make contact if you are interested in pursuing research in this area.
