Scientists Realize High-Fidelity Single-Qubit Gates on Neutral Atoms[Dec 14, 2018]

Prof. ZHAN Mingsheng's group from Wuhan Institute of Physics and Mathematics (WIPM) of Chinese Academy of Sciences recently made progress in quantum information processing with optically trapped neutral atoms. Utilizing the magic-intensity optical trapping technique, they constructed a novel atomic quantum register, in which the fidelity of global single-qubit gates was achieved higher than 99.99% for the first time.

Researchers Develop A High-performance Measuring Instrument to Look into the Haze[Dec 14, 2018]

Chinese scientists at Anhui Institute of Optics and Fine Mechanics (AIOFM) have developed a high-performance instrument to track Gaseous nitrous acid (HONO) and NO2, both playing the important role in haze formation. They call it incoherent broadband cavity enhanced absorption spectrometer (or IBBCEAS), it could detect an extremely small amount of key trace gas in atmosphere and the experimental results would be obtained in a very short time of only several seconds.

A Versatile Method to Prepare Functional Hydrogel Coatings[Dec 14, 2018]

Biomedical materials with functional surfaces are desired for practical applications. Hydrogels—extremely versatile materials used in wet and biological environments—could be used to modify material surfaces. Recently, Prof. ZHOU Feng and colleagues from Lanzhou Institute of Chemical Physics (LICP) presented a universal method to form functional hydrogel coatings on a wide range of substrate materials.

Researchers Identify Brain Cells Gating Itch-scratching Cycle[Dec 14, 2018]

In a recent study published in Neuron, Dr. SUN Yangang's lab at the Institute of Neuroscience of the Chinese Academy of Sciences demonstrated that tachykinin 1 (Tac1)-expressing neurons in the periaqueductal gray (PAG) facilitate the itch-scratching cycle via descending regulation.

More Than Air: Researchers Fine-tune Wind Farm Simulation[Dec 13, 2018]

A collaborative research team based in Beijing, China, is working to better understand the effect wind farms have locally and globally by examining the performance of predictive models currently being used to forecast their effect. Wind power is on track to supply almost a fifth of the world’s demand for electricity by 2050, according to the Global Wind Energy Council.
