Racing to the Future: China's Quantum Leap in Cryptography

China plans to establish national standards for post-quantum cryptography within three years, emphasizing the strategic role of quantum technology. With the global push for secure algorithms against powerful quantum computers, China's focus includes homegrown cryptographic methods and prioritizes sectors like finance and energy for swift adaptation.

China aims to set national standards for post-quantum cryptography over the next three years, with significant investments in research, according to a leading expert. This move aligns with global efforts to develop encryption algorithms resilient against future quantum computers, which threaten to nullify existing digital security measures.

As outlined in China's recent five-year plan, quantum technology is now considered a key future strategic industry. The plan highlights quantum advancements alongside embodied AI, nuclear fusion, and brain-computer interfaces, aiming for a scalable quantum computer. The U.S. finalized its initial post-quantum cryptography standards in 2024, targeting full migration by 2035.

Wang Xiaoyun of Tsinghua University emphasized the importance of migrating finance and energy sectors to post-quantum cryptography due to their data sensitivity. Unlike many international researchers, Chinese experts focus on 'structureless lattice' algorithms, such as S-Cloud+, to avoid security degradation prevalent in some existing methods. In a groundbreaking move, China launched an open-source operating system for quantum computers last month, state media reported.
