I am a professor in the Warwick Physics Department and the founding director of Warwick Quantum, a new interdisciplinary initiative for Quantum Technology.
My group creates quantum science and technology based on nitrogen-vacancy colour centres in diamond. We are a part of the Quantum Technology Lab in Warwick, the Quantum Computing and Simulation (QCS) Hub and the Centre for Doctoral Training in Diamond Science and Technology (DST).
Materials such as diamond contain electron and nuclear spins which store quantum information for a long time. We use single nitrogen vacancy centres (NVC) in diamond for magnetometry and to explore the possibility of building a quantum computer. We also use large ensembles of NVC for magnetometry.
We levitatate micro-diamonds in vacuum because we would like to test whether these can be in a quantum superposition of two places at once. This could lead to a test of the quantum nature of gravity.
