China launches mass production of silicon-28: a breakthrough for quantum computing
China National Nuclear Corporation (CNNC) has announced the start of serial production of silicon-28 with isotopic purity exceeding 99.99%. This is a landmark event — for the first time in China's history, large-scale, fully independent production of this material has been organized.
The specialized silicon-28 isotope is critically important for the development of silicon-based quantum computers. Its key advantage is the ability to significantly reduce the level of magnetic interference, which directly enhances the stability and coherence time of qubits. In ordinary natural silicon, impurities (particularly the silicon-29 isotope) create noise and destabilize quantum states.
Purification to the level of 99.99% and above is the technological equivalent of alchemy in microelectronics. Previously, a monopoly on such production effectively belonged to several Western companies. Now Beijing is closing this critical gap in the supply chain of high-tech raw materials.
Analytical commentary from Cryptalist expert
This is not just news from a materials science laboratory. It is a direct signal of China's strategic intention to take a leading position in the quantum computing race. Control over the production of ultra-pure silicon-28 gives Beijing an undeniable advantage: the ability to scale quantum processors without relying on external supplies. In a world where quantum technologies promise to break modern cryptographic standards (including algorithms protecting blockchains), such a move is an investment in future economic and technological security. The DeFi and cryptocurrency industries should closely monitor these developments, as they directly impact the timeline for transitioning to post-quantum cryptography.
