Highly sensitive, high spatial resolution quantum precision measurement technology
Quantum precision measurement is an important current research area in quantum information science and is an emerging technology that breaks through the limits of classical measurement. Magnetic properties as one of the fundamental properties of matter, and its microscopic imaging is an important research direction in experimental physics. And with the rise of magnetic storage, spintronics, and other fields, the microscopic study of magnetism has put forward completely new technical requirements. In recent years, a unique defect structure Nitrogen-Vacancy (NV) center in diamonds, has attracted the attention of researchers.
Quantum precision measurement technology based on the NV center in diamond
Scanning probe microscopy based on NV-center in diamond fully combines the advantages of high-sensitivity magnetic detection of light-probing magnetic resonance technology and ultra-high-resolution imaging technology of atomic force microscopy to achieve nanoscale, high-sensitivity, nondestructive, quantitative magnetic properties of scanning imaging, which plays an important role in superconducting magnetic vortex imaging and two-dimensional material magnetic imaging research. Based on the profound technical accumulation in the field of quantum precision measurement, and after extensive research, long-term exploration, and a full understanding of current research needs, the R&D team of CIQTEK has developed the commercialized Cryogenic Quantum Diamond Atomic Force Microscope (CQDAFM).
