Researchers from the University of Science and Technology of China and the University of Hong Kong, constructed a coherent superposition of quantum evolution with two opposite directions in a photonic system, and confirmed its advantage in characterizing input-output indefiniteness.
In a study published online in Nature, a research team from the University of Science and Technology of China has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM).
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.
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.
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.
