Abstract The Nitrogen-Vacancy (NV) defect in diamond is a unique quantum system that
offers precision sensing of nanoscale physical quantities at room temperature beyond the
current state-of-the-art. The benchmark parameters for nanoscale magnetometry
applications are sensitivity, spectral resolution, and dynamic range. Under realistic
conditions the NV sensors controlled by conventional sensing schemes suffer from
limitations of these parameters. Here we experimentally show a new method called …
