China is making significant strides in the field of post-quantum cryptography, a critical area of research as the global race to secure data against the threat of quantum computing intensifies. According to Wang Xiaoyun, a professor at Tsinghua University’s Institute for Advanced Study, the country is on track to finalize national standards for post-quantum cryptography within the next three years. This move aligns with China’s broader strategic push to dominate key technological frontiers, including quantum computing, embodied AI, and nuclear fusion.

China’s Quantum Ambitions and Strategic Priorities

China’s new five-year plan, revealed last week, positions quantum technology as a core strategic industry, placing it alongside other advanced sectors such as embodied AI and brain-computer interfaces. The plan also sets a clear objective: to develop a scalable quantum computer, a goal that underpins the urgency of advancing post-quantum encryption standards.

The U.S. finalized its first set of post-quantum cryptography standards in 2024, aiming to complete the full industry migration by 2035. In contrast, China last year issued a global call for the development of new standards, signaling its intent to shape the global framework for quantum-resistant encryption.

Wang Xiaoyun emphasized that the finance and energy sectors will be the first to transition to post-quantum cryptography, given the high sensitivity of the data involved. She noted that the next three to five years could witness explosive growth in the post-quantum cryptography industry in China.

Unlike many international researchers, who have focused on algebraic lattice-based algorithms, Chinese cryptographers are developing ‘structureless lattice’ algorithms such as S-Cloud+. According to Wang, international standards based on algebraic lattices have some degree of security degradation, whereas structureless cryptographic algorithms are largely free from this issue.

China’s Open Source Quantum Operating System

In a notable first, China recently released a homegrown operating system for quantum computers that is open source and available for online download. This development, reported by state media, marks a significant step in China’s effort to build a strong domestic ecosystem for quantum computing and post-quantum cryptography.

Global technology leaders such as Google have long urged governments to accelerate the adoption of post-quantum cryptography, recognizing the existential threat quantum computers pose to current encryption methods. The U.S. Trump administration’s recently released cyber strategy reiterates the country’s commitment to maintaining its dominance in post-quantum cryptography and artificial intelligence.

Meanwhile, South Korea has outlined its own roadmap, planning to implement post-quantum cryptography across a wide range of industries by 2035. The country has already launched a pilot transition plan for critical sectors like energy and healthcare between 2025 and 2028.

Implications for Global Cybersecurity and Industry

China’s push into post-quantum cryptography is not only a matter of national security but also has profound implications for the global economy and digital infrastructure. As quantum computers become more powerful, current encryption methods such as RSA and ECC will become obsolete, leaving sensitive data vulnerable to decryption.

Wang Xiaoyun highlighted that the transition to post-quantum cryptography is inevitable. ‘The threat is real,’ she said. ‘If we do not prepare now, we will be at a severe disadvantage in the next decade.’

For ordinary users, the shift to quantum-resistant encryption may be invisible at first, but it will be critical in securing everything from banking transactions to healthcare records. The financial sector, in particular, is expected to be one of the first to adopt these new standards, given the high stakes involved in protecting digital assets and personal information.

The Chinese government’s investment in this area is part of a broader strategy to reduce reliance on foreign technology and establish domestic leadership in emerging fields. This includes not only the development of algorithms but also the creation of supporting infrastructure such as quantum computers and open-source operating systems.

Experts predict that the next three to five years will be a key period for the post-quantum cryptography industry in China. With increasing government support and private sector involvement, the country is well-positioned to become a global leader in this critical domain.

As the world moves closer to the quantum era, the race to develop secure encryption methods has only just begun. China’s aggressive strategy in this area could redefine the global landscape of cybersecurity and digital innovation in the years to come.
