Researchers have first certified device-independent genuine multipartite entanglement and invented a new method to certify genuine multipartite entanglement without making any assumptions on the internal functioning of the measurement device.
A Chinese team has realized, for the first time in the world, the ultra-high-precision time-frequency dissemination, a technique to monitor and synchronize clocks, over a long distance, more than 100 kilometers.
China is now the only country in the world, that has achieved major breakthroughs in both photonic and superconducting quantum computing, represented by computer prototypes "Jiuzhang" and "Zuchongzhi No.2" respectively.
Researchers from the University of Science and Technology of China and their collaborators developed a system that can not only promise twin-field quantum key distribution over a 658-km optical fiber, but also sense channel vibration with an accuracy better than one km.
Prof. PAN Jianwei and Prof. ZHAO Bo from the University of Science and Technology of China, collaborating with Prof. BAI Chunli from Institute of Chemistry, found strong evidence for association of triatomic molecules after applying ratio-frequency (rf) pulse to an ultracold mixture of 23Na40K and 40K near Feshbach resonance.
A group led by Prof. PAN Jianwei from the University of Science and Technology of China and his collaborators developed sophisticated setup and measured the second sound attenuation near quantum criticality. The experimental results proved the existing dynamic scaling theory while opening up the path to systematic exploration of quantum critical region.
