Quantum microscopy using single defects in diamond

Dr Michael Barson
Laser Physics Centre, ANU

The field of microscopy has seen multiple noteworthy and major technological shifts, from optical microscopes to electron and atomic force microscopes (AFM). A new and emerging platform is the quantum microscope, where the measurement probe itself is a quantum object, allowing for enhanced sensitivity and the capability to image quantum effects.

The nitrogen-vacancy (NV) centre in diamond is a proven tool for such a microscope. Its unique room temperature properties and atom-like size allows for sensing and imaging at the nanoscale in ambient conditions.
I will talk about the work done here at ANU to develop such a quantum microscope. To do this, we have married AFM and confocal microscopy techniques with quantum measurement protocols.
