The OXFORD team has a strong track record in combining materials science for quantum technologies with foundational questions about quantum reality. We have world-leading expertise in rare-earth molecular materials, including optical and magnetic characterization. We have a track record of spin resonance in ensembles and devices. We devised one of the first proposals for encoding single qubit information in spin ensembles, which we subsequently tested with in a semi-classical proof-of principle. With others we formulated the Oxford Questions on the foundations of quantum physics. We collaborate with experts in optical micro-cavities (J. Smith), superconducting qubits (P. Leek) and the theory of networked quantum computing (S. Benjamin).
