Recently, researchers from the University of Science and Technology of China (USTC) reveals that not all forms of quantum nonlocality guarantee intrinsic randomness. They demonstrated that violating two-input Bell inequalities is both necessary and sufficient for certifying randomness, but this equivalence breaks down in scenarios involving multiple inputs. This finding has been published in Physical Review Letters.

A research team from the University of Science and Technology of China (USTC), in collaboration with several research institutions in China and South Africa, has developed the world’s first quantum microsatellite and demonstrated real-time quantum key distribution (QKD) between the satellite and multiple compact, mobile ground stations.

A research team led by Prof. PAN Jianwei, Prof. WAN Zhensheng and Prof. DENG Youjin from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences observed counterflow superfluidity in two-component Mott insulator for the first time. The study was published in Nature Physics.

Recently, a research team led by Prof. LI Chuanfeng from the University of Science and Technology of China (USTC) achieved a breakthrough in quantum photonics. They developed an on-chip photonic simulator capable of simulating arbitrary-range coupled frequency lattices with gauge potential. This study was published in Physical Review Letters.

A research team led by Prof.GUO Guangcan from the University of Science and Technology of China (USTC),collaborated with Prof.Jiannis K.Pachos from University of Leeds,has experimentally calculated the Jones polynomial based on the quantum simulation of braided Majorana zero modes.The research team determined the Jones polynomials of different links through simulate the braiding operations of Majorana fermions.This study was published in Physical Review Letters.

Prof. YU Sixia, Associate Researcher SUN Liangliang and ZHOU Xiang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. XU Zhenpeng from Anhui University (AHU) and Armin Tavakoli from Lund University, proposed an approach to quantify entanglement using the standard entanglement witness procedure under three common experimental scenarios. Their work was published in Physical Review Letters.
