Glass-nanodiamond photonic approach for quantum sensing platform based on Nitrogen-Vacancy centers.

Negatively charged Nitrogen-Vacancy (NV) center in diamond is a flourishing research area that, in recent years, has displayed remarkable progress. The ability to manipulate NV electron spin optically under ambient conditions offers great potential for realizing emerging applications in nanoscience, benefiting a range of fields from bioimaging to quantum magnetic field and temperature sensing. The seminar will cover current status on our work demonstrating experiments with dried ND suspensions aiming at the development of photonic sensors with imaging feasibility. I will discuss our demonstrations of remote-sensing capability of the high-numerical-aperture imaging fiber (IFB) bundle with nanodiamonds deposited on its end facet.
