Diamond-based quantum sensing

Diamond has emerged as a unique material for a variety of applications, both because it is very robust and because it has defects with interesting properties. One of these defects, the nitrogen-vacancy center (NV center), has a single spin associated with it that shows quantum behavior up to room temperature. Our group is harnessing the properties of single NV centers for high resolution magnetic sensing applications.

In this talk, I will discuss the basics of diamond-based quantum sensing and highlight some key applications pursued in our laboratory, including the development for advanced sensing protocols for high-resolution spectroscopy of magnetic fields, as well as their application to nanoscale nuclear magnetic resonance experiments. I will also give an outlook on scanning imaging of currents and magnetism in two-dimensional materials and recent advances made to the scanning probe technology that enables these experiments.
