View MoreImages are ubiquitous in our lives and are a fundamental and indispensable medium for the dissemination of information. Imaging is a direct means of acquiring images and can be classified according to the different imaging wavelengths as visible, radar, infrared, and terahertz imaging. With the further development of information technology, new demands are being placed on spatial resolution, signal-to-noise ratio, multispectral imaging performance, and the imaging environment. Single-pixel Imaging Technology With the increase in computer arithmetic power and the development of compressed perception theory, scientists have proposed a single-pixel imaging technique based on a computational imaging approach. This is a new imaging method that uses a single-pixel detector without spatial resolution and a spatial light modulator to obtain images by reconstruction. Compared with the traditional array detector imaging method, single-pixel imaging has the advantages of high sensitivity and interference resistance and has obvious advantages in the fields of very weak light imaging, non-local imaging, special band detection without large surface array detectors, etc. It has very broad application prospects in many fields such as nuclear magnetic resonance, aerospace remote sensing, and terahertz imaging.

Comm. 410, 287-291 (2018) Single Pixel Photon Imaging Teaching Instrument Although computational imaging, represented by single-pixel photon imaging, is promising, there is still a lack of experimental teaching content at the undergraduate level. In order to improve the relevant curriculum and help students develop their scientific research skills, CIQTEK, in collaboration with Professor Qing Zhao's team from the Quantum Technology Research Centre of Beijing University of Technology, has created a single-pixel photon imaging teaching instrument. The product is a teaching instrument based on the theory of compressed perception and photon counting imaging technology, using digital micromirror devices to accomplish rapid imaging of random spatial light-modulated target objects. The product takes advantage of the sparse signal characteristics of the compressed sensing technique to go beyond the traditional Shannon sampling theorem and can restore images with high spatial resolution and high signal-to-noise ratio in very low light conditions with fewer measurements. CIQTEK Launched Single Pixel Photon Imaging Teaching Instrument The single-pixel photon imaging teaching instrument has a wealth of hardware modules to support students' hands-on adjustment and construction, facilitating students' understanding of spatial light modulation techniques and equipment usage, understanding the principle of compressed perception and imaging methods, and knowing the ch...

Clauser, and Austrian physicist Anton Zeilinger for their experiments with entangled photons that proved Bell's inequality does not hold, and in doing so, pioneered the science of quantum information. Alain Aspect (Left), John F. Clauser (Mid), Anton Zeilinger (Right) Image source: Nobel Prize official website Their experiments laid the foundation for the current revolution in quantum technology and really pushed quantum mechanics from theory to application, as mentioned in the official evaluation. This is the first time that a Nobel Prize has been awarded to quantum information science. Quantum Technology Changing the World Born in the early 20th century, quantum mechanics is one of the most significant scientific revolutions in human history. It has opened the door to the microscopic world for mankind, overturned the perspective of human cognition of the world, and given rise to a series of major technological inventions such as semiconductors, lasers, nuclear energy, superconductivity, nuclear magnetic resonance, and satellite navigation, which have fundamentally changed the way of life and the level of social development of mankind. In the 1990s, with the tremendous progress in quantum regulation technology, mankind was able to actively and precisely manipulate the quantum state of microscopic particles, thus ushering in a breakthrough in quantum information technology. These include quantum secrecy communication technology to ensure information security, quantum computing technology to increase the speed of computing, and quantum precision measurement technology to improve the accuracy of measurement.

View MoreProf. Dr. Jiangfeng Du and Prof. Dr. Fazhan Shi of the Chinese Academy of Sciences (CAS) Key Laboratory of Microscopic Magnetic Resonance, in collaboration with Prof. Dr. Haiming Wei of the School of Life Sciences, University of Science and Technology of China (USTC), have made important progress in the biomedical application of diamond nitrogen-vacancy (NV) center quantum precision measurement technology. The first immunomagnetic imaging technique for tumor tissues was established to achieve magnetic imaging at the tissue level with micron resolution. It has the advantages of high stability, low background, and absolute quantification of tumor markers, and achieves both magnetic and optical multimodal imaging. > The research results were published in the Proceedings of the National Academy of Sciences on January 26, 2022, under the title "Immunomagnetic microscopy of tumor tissues using quantum sensors in diamond" [ Proc Natl Acad Sci U S A 119(5), e2118876119 (2022)]. Cancer is currently one of the most deadly diseases in humans. Research on the molecular mechanism of cancer and early and accurate clinical diagnosis is the basis for effective treatment. The imaging of tumors at the tissue level is a key part of cancer research and clinical diagnosis, especially in the diagnosis of cancer, although there are various medical imaging methods, pathological tissue testing is still the "gold standard" for cancer diagnosis. Therefore, the development of histopathological methods is of great biological and clinical importance. The current mainstream pathological tissue imaging methods include H&E staining, immunohistochemistry, and immunofluorescence, which are mainly based on optical imaging. They are susceptible to problems such as strong optical background, signal instability, inaccurate quantification, and inability to share different optical methods, which in turn affect the accuracy of histopathological detection. Figure 1 Device and principle of immunomagnetic microscopy of tumor tissue Magnetic resonance imaging (MRI) is expected to address these shortcomings of optical imaging. However, traditional MRI is limited by low sensitivity and low spatial resolution, which makes it difficult to be applied to imaging at the tissue level with micron resolution. In the recent work, the research team used a newly developed quantum magnetic sensor, NV center, an atomic defect in diamond single crystals) in diamond, to build wide-field magnetic imaging equipment independently, combined with quantum precision measurement and immunomagnetic labeling technology, to achieve micron resolution tumor tissue magnetic imaging for lung cancer detection. Specifically, the research team first developed a tissue-level immunomagnetic labeling method to specifically label 20 nm diameter superparamagnetic particles with target protein molecules such as PD-L1 in tumor tissues...
