Gavin Morley is a Royal Society University Research Fellow and an Associate Professor (Reader) in the Warwick University Physics Department. His research group builds quantum experiments and technologies based on magnetic resonance with electron and nuclear spins in silicon and diamond crystals. He leads a project aiming to test the macroscopic limits of the quantum superposition principle. His team have recently built the world’s most accurate and precise electron paramagnetic resonance spectrometer and have set up three diamond experiments: optically levitated nanodiamonds, nanoscale magnetometry with single spins and ensemble magnetometry towards medical applications.

09:45-10:15 Ab initio theory of vacancy-impurity defects as quantum bits in diamond

Dr Adam Gali, Wigner Research Centre for Physics, Hungary

Abstract

Paramagnetic and luminescent point defects in diamond could be very prospective for quantum information processing. Understanding the properties of nitrogen-vacancy (NV) centre in diamond from first principles calculations contributed to the development of NV based quantum technology. Although, NV centre has been successfully employed in quantum sensing and quantum communication protocols, not all the magneto-optical properties are ideal for certain quantum technology applications. The ab initio toolkit developed in Dr Gali's research group is a powerful method to search for alternative vacancy-impurity defects in diamond for target magneto-optical properties for given quantum technology applications. Identification and characterisation of vacancy-impurity defects in diamond are presented with various zero-phonon-lines, Debye-Waller factors and energy gaps between the spin levels.
