Overview of Academic Research
We have conducted systematic research in the field of quantum computing and quantum sensing, with a focus on breakthroughs in quantum material preparation and quantum applications based on diamond nitrogen-vacancy (NV) centers. The following key achievements have been made:Using the microwave plasma chemical vapor deposition (MPCVD) method, we successfully prepared electronic-grade diamond single crystals and fabricated a series of samples, including NV centers and NV center arrays, for spin coherence and quantum sensing studies. We developed samples with ultra-high NV center concentrations, reaching the ppm level, with plans to further increase this to over 10 ppm while maintaining excellent coherence properties. These advancements are applicable to ultra-precision quantum sensing and detection. Additionally, we achieved the first fiber-integrated NV center magnetometer and NV center array temperature sensors. Related findings have been published in journals such as Applied Physics Letters and Physical Review B.
Core Research Directions:
1.Preparation and physical property studies of high-quality diamond single crystals
