Nitrogen-vacancy (NV) centers in diamond have superior physical properties, and their quantum coherence is preserved even at room temperature. To achieve an ideal quantum sensor for scalable applications, the technical challenges in the sensor materials and the quantum control techniques are developed. Moreover, sensor systems for the biological/ medical systems and battery/ power electronics are introduced.

Nitrogen-vacancy (NV) centers consisting of a nitrogen atom and a lattice vacancy in diamond have superior physical properties, and their quantum coherence is preserved even at room temperature. To achieve an ideal quantum sensor for scalable applications, the technical challenges in the material and the quantum control techniques are discussed. Moreover, sensor systems of biomagnetic field and EV battery monitoring are introduced.

The NV center in diamond has been attracting attention from the viewpoint of the application of ultrasensitive sensors and quantum information devices. One of the most significant properties is that the electron spin of the NV center in diamond exhibits the longest spin coherence time at room temperature among solid-state electron spin systems, which is crucial for achieving high sensitivity. This paper describes the basics of diamond-based quantum sensors and our recent research.
