(Upstream News)The latest development of quantum computing research: A new generation of quantum chips can improve the quantum error-correcting function. The internationally renowned academic journal Nature recently published a quantum computing paper saying that the latest generation of quantum chips of Google Quantum AI can realize the quantum error-correcting function of suppressing errors below a critical threshold, which is considered to be a necessary condition for realizing the practical application of quantum computing in the future. Researchers believe that the performance expansion of the latest generation of quantum chips may promote the operational requirements of large-scale fault-tolerant quantum computing. (Zhongxin. com)
