Outline of Final Research Achievements

We succeeded in creation of nitrogen-vacancy (NV) centers with simultaneously-controlled orientations and positons using nitrogen-doped isotopically-enriched chemical vapor deposition on microfabricated diamond substrate. We demonstrated high-sensitive AC magnetic field sensing with the preferentially-oriented NV ensemble using home-build wide-field optically-detected magnetic resonance microscope. We proposed and experimentally demonstrated highly-sensitive AC magnetic field by simultaneous quantum control of electric spins of NV centers using multi-frequency microwave.
