This technology achieves high-precision quantum magnetic field measurement from 0.01T to 1.5T based on the diamond nitrogen-vacancy (NV) color center quantum system. It adopts optically detected magnetic resonance to precisely determine magnetic field strength through quantum energy level differences and utilizes NV color center crystal axis orientation for magnetic field direction identification, providing a revolutionary solution for solid-state quantum magnetic measurement.
