China launches mass production of silicon-28: a breakthrough for quantum computing
China National Nuclear Corporation (CNNC) has announced the start of mass production of silicon-28 with an isotopic purity exceeding 99.99%. This event marks the first time in the country's history that this material has been independently produced on a large scale.
Silicon-28 is a critically important component for creating silicon-based quantum computers. Its unique properties allow for a significant reduction in the level of magnetic interference, which directly affects the stability of qubits — the basic elements of quantum computing systems. Improving qubit stability is one of the main challenges in the development of quantum technologies, and access to high-purity silicon-28 could give the Chinese industry a significant competitive advantage.
Previously, the production of such material was concentrated in the hands of a limited number of Western companies, creating dependence for Chinese research centers and technology giants. Now, with the launch of its own production, Beijing is not only strengthening technological sovereignty but also laying the foundation for the accelerated development of quantum computing — one of the key areas in the global race for computational supremacy.
Analytical commentary: This move by China is not just a local success but a signal of a reshaping of the global supply chain for critical materials. While the world is focused on quantum algorithms and software, control over the physical base — isotopically pure silicon — is becoming a new battlefield. For the crypto industry, this has long-term implications: stable quantum computers are capable of breaking existing cryptographic protocols, and China is clearly preparing for this reality faster than many expected.
