Hands-On Quantum Sensing with NV− Centers in Diamonds

The physical properties of diamond crystals, such as color or electrical conductivity, can be controlled via impurities. In particular, when doped with nitrogen, optically active nitrogen-vacancy centers (NV), induced. center is an outstanding quantum spin system that enables, under ambient conditions, optical initialization, readout, and coherent microwave control applications in sensing information. Under radio frequency excitation, the Zeeman splitting degenerate states allows quantitative measurement external magnetic fields high sensitivity. This study provides a pedagogical introduction to NV well step-by-step process develop test simple sensor based on significant potential for development highly compact multisensor systems.
