China launches mass production of ultra-pure silicon-28: a breakthrough for quantum computing
The China National Nuclear Corporation (CNNC) has officially announced the start of mass production of silicon-28 with isotopic purity exceeding 99.99%. This event marks the first independent large-scale production line for this material in China's history. For me, as an analyst, this is not just news from the semiconductor world — it is a direct signal of a shift in the global balance in the quantum technology race.
Why silicon-28 is critically important for the future
Silicon-28 is an isotope lacking nuclear spin, making it an ideal platform for creating stable qubits in silicon quantum computers. The main problem with ordinary silicon is the presence of the silicon-29 isotope, which creates magnetic interference and disrupts quantum states. Using ultra-pure silicon-28 allows for a sharp reduction in decoherence levels and an increase in qubit coherence time. This is a direct path to scalable and commercially viable quantum computers.
The launch of mass production in China is not only a technological but also a geopolitical move. Previously, supplies of such material were limited and dependent on Western manufacturers, primarily from Russia and the United States. Now Beijing gains autonomy in a critically important link of the supply chain for quantum systems.
Impact on the crypto industry and blockchain
At first glance, the production of silicon-28 may seem far removed from cryptocurrencies. However, I see a direct connection: stable qubits are the foundation of future quantum attacks on encryption algorithms, including ECDSA used in Bitcoin and Ethereum. Mass production of this material accelerates the emergence of powerful quantum machines, making the issue of post-quantum cryptography not just academic but urgent for the entire industry.
My expert conclusion: China is not just catching up — it is purposefully building infrastructure for quantum supremacy. For the crypto community, this means the window of opportunity for migrating to quantum-resistant algorithms is narrowing. Investors and developers should already pay attention to projects working on post-quantum solutions — otherwise, security risks will become unacceptably high within the next 5-7 years.
