Quantum Sensing with Diamond Colour Centres

Diamonds hosting fluorescent colour centres have gained prominence in quantum metrology as highly versatile sensors. While the use of nitrogen-vacancy (NV) centres for magnetometry is particularly well-known, NV centres and other colour centres [e.g. silicon-vacancy (SiV) centres] can also be applied in the sensing of other physical quantities such as temperature and strain.

​

We are pursuing the application of diamond-based sensors for use in scanning probe microscopy to achieve high-sensitivity quantum sensing with nanometric resolution. This would allow us to explore a variety of interesting nanoscale materials and surface physics, and can potentially be applied in the characterization of nano-electronics and the development of advanced metamaterials.

​

We are exploring both the use of commercial probes with NV centres embedded in diamond nanopillars, as well as the development of customised probes with tailored geometry and colour centre composition.
