China reaches mass production of key isotope in quantum computing, Beijing says

AI Summary

China has achieved mass production of a critical isotope, silicon-28, essential for silicon-based quantum computers. This breakthrough by China National Nuclear Corporation marks progress in reducing dependence on foreign technology for strategic tech developments.

China has achieved a breakthrough in production of an ultra-pure form of silicon, a critical material needed to build silicon-based quantum computers, as Beijing accelerates its drive to cut reliance on foreign technology in strategic areas. State-owned nuclear giant China National Nuclear Corporation (CNNC) said on Monday that one of its research institutes had successfully mass-produced a high-purity silicon-28 isotope with an isotopic abundance above 99.99 per cent. The achievement marked...
