Recently, the research team of the China Electronics Technology Group Corporation Industrial Foundation Research Institute and the Chinese Academy of Sciences have successfully developed a highly sensitive integrated diamond nitrogen vacancy color center quantum magnetometer and the first diamond nitrogen vacancy color center maser in China. "The diamond nitrogen vacancy color center, a solid-state quantum spin system, has the advantages of easy initialization and readout, controllability, and long coherence time. It has great application prospects in the fields of quantum precision measurement and quantum computing." Technical experts from the research team of the Industrial Foundation Research Institute said that after years of hard work, they have successfully developed an integrated diamond quantum magnetic sensor with a sensitivity that has reached the international advanced level, and the maximum quantum oscillation power of the diamond nitrogen vacancy color center maser has reached the international leading level. In the future, the technical team will further promote the performance improvement and integration of sensors, promote the industrialization of quantum sensors based on solid-state spin systems, and apply them to industrial flaw detection, geological resource exploration, deep space communications, biological testing, materials research and other fields.
