The current deep neural network system (such as ChatGPT) can quickly improve energy efficiency by 100 times in training, and "future improvements will greatly increase by several orders of magnitude. Scientists from MIT and other institutions have demonstrated a new optical neural network training method that can crush state-of-the-art electronic microprocessors.Moreover, the computational density...
Recently, the team led by Academician Guo Guangcan from the University of Science and Technology of China has made significant progress in the research of quantum elliptical polarization imaging. The research group of Professor Shi Baosen and Associate Professor Zhou Zhiyuan combined high-quality polarization entangled light sources with classical polarization imaging technology to observe the bir...
Recently, Zhang Xin's research team from the Institute of Oceanography, Chinese Academy of Sciences, based on the in-situ laser Raman spectroscopy technology, made new progress in the in-situ recognition and quantification of methane carbon isotopes by using the significant differences in the Raman spectra of methane carbon isotopes (13CH4 and 12CH4). The relevant results were recently published i...
Recently, the team led by Wang Rui from the Future Industry Research Center and the School of Engineering at Xihu University has made significant breakthroughs in the field of flexible stacked solar cells. They have successfully stacked perovskite and copper indium gallium selenide materials together, resulting in a photoelectric conversion efficiency of 23.4%. The related research paper was recen...
