The world's first commercial low-temperature quantum diamond atomic force microscope is officially unveiled
At the first national Quantum Precision Measurement Enabling Industry Development Conference, the world’s first commercial low-temperature version of the quantum diamond atomic force microscope was officially unveiled. The microscope was independently developed by Guoyi Quantum Technology (Hefei) Co., Ltd., which marks an important breakthrough in the industrial development of my country's quantum precision measurement technology.
Magnetism is one of the basic properties of matter, and its microscopic imaging is an important direction in experimental physics research. By in-depth study of the microscopic magnetic properties of materials, scientists can gain an in-depth understanding of the material's structure, electronic properties and interactions, which is of great significance for guiding the development of new magnetic storage materials and superconducting materials.
He Yu, chairman of Guoyi Quantum, 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 in a wide temperature range, with high spatial resolution at the nanometer level and ultra-high detection sensitivity of a single spin.
"It is mainly used to detect the surface magnetic properties of materials, and will provide a new method for research in life sciences, materials science, condensed matter physics and other fields in my country," He Yu said.
Quantum precision measurement technology has the characteristics of high technology, high efficiency and high quality. It uses quantum characteristics (energy level transition, coherent superposition, quantum entanglement) to gain the ability to break through the limits of classical measurement technology, and is expected to improve measurement accuracy, sensitivity, and resolution. surpass existing technology in other aspects. The industry believes that quantum precision measurement is the next “closest to industry” direction in the field of quantum information technology.

Peking University research team realizes fully programmable topological photonic chip for the first time.
According to news on May 22, the team of Researcher Wang Jianwei, Professor Hu Xiaoyong, Professor Gong Qihuang and their collaborators from the " Extreme Optics Innovation Research Team" of the Institute of Modern Optics , School of Physics , Peking University, and their collaborators recently proposed and implemented a completely integrated optical system based on large-scale integrated optics. Programmable topological photonic chip .
By integrating a reconfigurable optical micro-ring cavity array on a large scale on a silicon chip, researchers have for the first time realized an arbitrarily programmable optical Floquet artificial atomic lattice, which can independently and precisely control each artificial atom and atom- Interatomic coupling (including its random but controllable disorder) has led to a series of experimental studies on a single chip including dynamic topological phase transitions, multi-lattice topological insulators, statistically relevant topological robustness, and Anderson topological insulators. .
This work broadens the boundaries of topological photonics, making it highly reconfigurable and programmable for the first time, providing a new way to study topological material science and develop topological photonics technology.
The relevant research results were published today (May 22, 2024) in the journal "Nature Materials" under the title "A programmable topological photonic chip".
So is this like a FPGA for photonic chips?
Incredible! When you think that the liver is the chemistry powerhouse of the human body, if it is compatible with pigs it makes me wonder what a little distance we are from... yeah... pigs!!!
