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 in two Centres for Doctoral Training (CDTs): Integrated Magnetic Resonance (iMR) and 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.
The EPR spectrometer we have built operates at the high magnetic field of 14 T, and can measure very sharp EPR resonances.
We have proposed and demonstrated the optical levitatation of nano-diamonds because we would like to test whether these can try out being in two places at once. These would be the heaviest objects to have demonstrated a spatial superposition.
