Abstract: In recent years, the rapid development of quantum information science has promoted the research of various quantum sensing technologies and produced many important results, which has had an important impact in the field of precision measurement. The sensing technology based on solid-state diamond NV color center electronic spin detection can be traced back to the basic quantum physical principles, and has important research value in the measurement standards of various sensing fields such as magnetic field, electric field, temperature, and pressure. The excellent properties of diamond NV color centers make reliable, stable and high-precision sensing applications possible in harsh environments. Taking its application in the field of temperature measurement as an example, this paper focuses on the development of NV color center spin detection principles and methods in the past ten years, and discusses the important research significance of solid-state quantum temperature measurement in combination with the latest research results.
