Nitrogen-vacancy (NV) centers in diamond have attracted high attention in recent years and are now considered among the most promising platforms for quantum sensing. Their remarkable properties including optical spin readout, long coherence times, and room-temperature operation have enabled groundbreaking demonstrations such as the detection of nanoscale nuclear spin signals. Despite these advances, many opportunities remain to further exploit shallow NV centers for advanced quantum technologies.

I will present two approaches for exploring their potential. First, I will discuss hybrid materials composed of rare-earth-doped thin films combined with diamond hosting shallow NV centers. Nanoscale interactions between these emitters may enable the development of hybrid platforms combining complementary optical and spin properties, opening new perspectives for light–matter interfaces. Second, I will focus on the integration of single shallow NV centers into diamond scanning probes for high-performance nanoscale sensing. Although these systems already demonstrate exceptional sensitivity, shallow NV centers remain strongly affected by surface-induced defects and noise. I will present a systematic study aimed at understanding these interactions to identify pathways toward improved performance.
