A team led by Prof. GUO Guangcan from University of Science and Technology of China, collaborating with the researchers from the South University of Science and Technology of China and Chongqing Institute of Green and Intelligent Technology, made progress in the research of basic problems of quantum mechanics using machine learning techniques.
Recently, the team led by Prof. GUO Guangcan from the University of Science and Technology of China first demonstrated the resilient effect of optical quantum coherence to transversal noise, and verified that the measurement precision of entangled Greenberger-Horne-Zeilinger (GHZ) state probes in transverse noise can still beat the standard quantum limit.
Fluoride crystals can be ideal optical and photonic materials due to their low phonon energy, high transmittance in wide wavelength range and high solubility of rare earth ions. A research team led by Prof. ZHANG Long from Shanghai Institute of Optics and Fine Mechanics has recently prepared the glass ceramics in perfluoride system.
Dr. ZHOU Xiao from Yunnan Observatories of Chinese Academy of Sciences reported a new type of orbital period variations in a close binary system V752 Centaurus. They monitored a very special target V752 Centaurus with the 0.60-m Helen Sawyer Hogg (HSH) Telescope in Argentina to get the multi-color light curves and times of light minimum, and reported that V752 Cen is a W-subtype totally eclipsed binary.
Recently, in a study published in The Astrophysical Journal Supplement Series, astronomers from Yunnan Observatories discovered the largest binary stars catalog with plentiful parameters from a uniform source. This catalog contains 12 parameters for 1320 binary stars, and all of them are discovered based on Kepler database and followed by Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST) spectral o...
Chinese scientists with Institute of Solid State Physics, Hefei Institutes of Physical Science developed chalcopyrite based compounds with record high thermoelectric performance. They developed a new method to modify the microstructure by design of domain area.
