A research team led by Prof. PAN Jianwei and Prof. ZHANG Qiang from the University of Science and Technology of China, and the collaborators, realized a set of random number beacon public services with device-independent quantum random number generators as entropy sources and post-quantum cryptography as identity authentication.
Scientists grappling with dating the age of the modern Yellow River, China's second-longest river, the "mother river" of the nation and the cradle of Chinese civilization, have made a breakthrough using a quantum technique.
Chinese scientists unveiled a quantum computer prototype named "Jiuzhang 3.0" with 255 detected photons on Wednesday, once again pushing the boundaries of photonics quantum computing technology. Led by the renowned Chinese quantum physicist PAN Jianwei, the research team has successfully accomplished this quantum computing feat, achieving a speed that is 10 quadrillion times faster in solving Gaussian boson sampling (GBS) problems compared to the world's existing fastest supercomputers.
A team led by Prof. GUO Guoping and Prof. CAO Gang from the University of Science and Technology of China, collaborating with Sigmund Kohler from Materials Science Institute of Madrid, developed a response theory applicable to strongly coupled and multiqubit systems.
The research team led by academician GUO Guangcan and Prof. REN Xifeng from the University of Science and Technology of China of the Chinese Academy of Sciences achieved quantum photonic sources at cryogenic temperatures based on the spontaneous four-wave mixing (SFWM) effect.
Researchers identified a potential security vulnerability in the modulator device of the QKD transmitter, and conducted quantum hacking attacks utilizing this vulnerability.
