A Chinese research team has realized the fractional quantum anomalous Hall state of photons for the first time by using an independently developed quantum experimental system, the University of Science and Technology of China (USTC) said on Monday.
Chinese researchers have taken a significant step toward unlocking the potential of quantum computing by achieving a breakthrough in simulating a complex quantum state using photons. Scientists at the University of Science and Technology of China, in Hefei, Anhui province, successfully realized the fractional quantum anomalous Hall state with photons, a feat previously only observed in electrons under specific conditions. Their findings were published in the journal Science on May 3.
A team of Chinese scientists have created the world's first memory-memory entanglement in a multi-node quantum network over a metropolitan area. The advancement has significantly extended the range of practical quantum entanglement networks, increasing it from a mere tens of meters to a substantial distance of tens of kilometers -- an enhancement spanning three orders of magnitude.
Prof. YU Sixia, SUN Liangliang and ZHOU Xiang from the University of Science and Technology of China of the Chinese Academy of Sciences, and the collaborators, proposed an approach to quantify entanglement using the standard entanglement witness procedure under three common experimental scenarios.
Researchers from the University of Science and Technology of China of the Chinese Academy of Sciences and Fudan University demonstrated for the first time that inequivalent mutually unbiased bases (MUBs) have different information extraction capabilities for quantum information processing.
A research group led by Prof. YANG Yong from the Hefei Institutes of Physical Science has revealed the role of neighboring adsorbate and quantum tunneling in the diffusion of hydrogen on graphene surface, which opens a possible way for ultrahigh precision measurement based on atomic systems, in particular, exploring the existence of a minimum length.
