Diamond Quantum Sensing
Professor Andrew Greentree

Quantum technologies have significant potential to revolutionize much of our modern lives. However, most of these technologies will be difficult to deploy in everyday situations due to their requirements for low temperature operation, or other specialized environments. Diamond containing the nitrogen-vacancy colour center stands out as a notable exception. Nitrogen-vacancy centers act as solid-state quantum systems, operating at room temperature and ambient magnetic fields.
The basic physics of nitrogen-vacancy diamond will be described, as well as recent work incorporating diamond into optical fibre for rugged sensing applications, and laser threshold magnetometry - a new method for creating nitrogen-vacancy center lasers - that promises unprecedented sensitivity and the hope for portable magnetoencephalography (MEG) helmets.
