Researchers Sergei Trofimov and Boris Naydenov from the
Helmholtz Center in Berlin have advanced quantum sensing technology using
Qnami Quantum Foundry diamond plates. In their work, they utilized nitrogen-vacancy (NV) centers in diamond, well-known for their applications in fields such as material science and biophysics. By combining confocal microscopy with atomic-force microscopy (AFM), they achieved nanoscale quantum sensing capabilities. Their setup, featuring platinum-coated and ferromagnetic cantilevers, enabled the sub-diffractional localization of NV centers with a lateral resolution of 13 nm, providing a powerful tool for precise characterization of NV diamonds or other color center materials.
