My group uses electron paramagnetic resonance (EPR) to investigate schemes for quantum technology, as well as studying fundamental physics with levitated nano-diamonds. We are a part of 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 have optically levitatated nano-diamonds because we would like to test whether these can be in a quantum superposition of two places at once.
