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 enhancements in sensitivity and resolution.
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 progress to develop such quantum microscopes. In particular, I will discuss some of my work performing nanoscale vector electric field imaging with sensitivity sufficient to measure single charges.

Dr Barson’s research focuses on using optically addressable solid-state defects to demonstrate quantum technology. In particular he uses the nitrogen-vacancy (NV) centre in diamond for nanoscale quantum microscopy, metrology and information processing. His work is at the intersection of high-resolution optical microscopy, magnetic resonance (EPR, NMR, etc) and nanometrology.

Dr Barson is a FLEET research fellow with FLEET’s Research Theme 3: Dynamically Controlled Dissipationless Systems
