Paper Abstract

Nitrogen vacancy (NV) quantum defects in diamond provide an unparalleled combination of magnetic field sensitivity and spatial resolution in a room-temperature solid, with wide-ranging applications in both the physical and life sciences.  NVs can be brought into few nanometer proximity of magnetic field sources of interest, such as single proton and electron spins while maintaining long NV spin coherence times, a large (~Bohr magneton) Zeeman shift of the NV spin states, and optical preparation and readout of the NV spin.  I will provide an overview of this nanoscale sensing technology and its diverse applications.
