China races ahead in post-quantum cryptography with bold new strategy

China is accelerating its push into post-quantum cryptography as part of a broader national strategy. The government's latest five-year plan highlights quantum technology, alongside fields like embodied AI and nuclear fusion. Experts predict rapid growth in the sector over the next few years.

Tsinghua University professor Wang Xiaoyun believes China's post-quantum cryptography industry will expand quickly within three to five years. The country is focusing on 'structureless lattice' algorithms, which Wang argues provide stronger security than traditional lattice-based methods used elsewhere.

China is also moving to finalise national standards for post-quantum cryptography within three years. This contrasts with the US and South Korea, where full industry adoption is not expected until 2035. The finance and energy sectors will be the first to upgrade their systems for better data protection.

In another key development, China has released an open-source operating system for quantum computers. The move underscores the country's push for independent innovation and tighter control over critical digital infrastructure.

China's approach to post-quantum cryptography sets it apart from other nations. By prioritising 'structureless' algorithms and fast-tracking standards, the country aims to secure its digital future. The finance and energy industries will lead the transition, with broader adoption expected in the coming years.
