China ahead on quantum technology
 

When a team of Chinese scientists beamed entangled photons from the nation's Micius satellite to conduct the world's first quantum-secured video call in 2017, experts declared that China had taken the lead in quantum communications.

New research suggests that lead has extended to quantum computing as well. In three preprint papers posted on arXiv.org last month, physicists at the University of Science and Technology of China (USTC) reported critical advances in quantum communication and quantum computing.
