On the 21st, the first National Quantum Precision Measurement Empowerment Industry Development Conference was held in Hefei, Anhui Province. At the meeting, the world's first commercial low-temperature version of the quantum diamond atomic force microscope was officially unveiled. This microscope was independently developed by Guoyi Quantum Technology (Hefei) Co., Ltd. (hereinafter referred to as "Guoyi Quantum"), and its release marks an important breakthrough in the industrialization development of quantum precision measurement technology in China. Magnetism is one of the fundamental properties of matter, and its microscopic imaging is an important direction in experimental physics research. By delving into the microscopic magnetic properties of materials, scientists can gain a deeper understanding of their structure, electronic properties, and interactions, which is of great significance for the development of new magnetic storage materials and superconducting materials. Guoyi Quantum Chairman He Yu introduced that the low-temperature version of the quantum diamond atomic force microscope is a quantum precision measurement instrument that combines diamond NV color center light detection magnetic resonance technology and atomic force microscope scanning imaging technology. It can be used for high-resolution, highly sensitive, quantitative and non-destructive magnetic measurements over a wide temperature range, with high spatial resolution at the nanoscale and ultra-high detection sensitivity for individual spins. "It is mainly used to detect the surface magnetic properties of materials, and will provide a new means for research in the fields of life sciences, materials science, condensed matter physics, etc. in China," He Yu said. Quantum precision measurement technology has the characteristics of high technology, high efficiency, and high quality. It utilizes quantum properties (energy level transitions, coherent superposition, quantum entanglement) to achieve the ability to break through the limits of classical measurement technology, and is expected to surpass existing technologies in measurement accuracy, sensitivity, resolution, and other aspects. The industry believes that quantum precision measurement is the next "closest" direction to the industry in the field of quantum information technology. It is understood that this conference, as the Anhui branch of 2024 "World Metrology Day", is jointly held by Anhui Provincial Market Supervision Bureau, Hefei Municipal Market Supervision Bureau, Chinese Academy of Sciences Self developed Scientific Instrument Application Demonstration Center, School of Physics, University of Science and Technology of China, and Guoyi Quantum.
