Quantum precision measurement technology, as a typical new productive force, features high technology, high efficiency, and high quality. This technology utilizes quantum properties such as energy level transitions, coherent superposition, quantum entanglement, etc., to achieve the ability to surpass the limits of classical measurement techniques, with the potential to exceed existing technologies in measurement accuracy, sensitivity, resolution, and more. It is widely believed in the industry that quantum precision measurement is the next "closest to industry" direction in quantum information technology.
Magnetism is one of the fundamental properties of matter, and its microscopic imaging is an important direction in experimental physics research. Through in-depth study of the microscopic magnetic properties of materials, scientists can gain a deeper understanding of the material's structure, electronic properties, interactions, which is of significant importance in guiding the development of new magnetic storage materials, superconducting materials, and more.
At the conference, the world's first commercial low-temperature quantum diamond atomic force microscope independently developed by National Instrument Quantum Technology (Hefei) Co., Ltd. made its debut.
It is reported that the low-temperature quantum diamond atomic force microscope is a quantum precision measurement instrument that combines diamond NV center optical detection of magnetic resonance technology with atomic force microscope scanning imaging technology. It can be used for high-resolution, high-sensitivity, quantitative non-destructive magnetic measurement in a wide temperature range from 2 Kelvin to 300 Kelvin, with nanoscale high spatial resolution and ultra-high detection sensitivity of single spins. It will provide a new means for research in fields such as life sciences, materials science, condensed matter physics in China.
