China launches mass production of ultra-pure silicon-28: a breakthrough for quantum computing
China National Nuclear Corporation (CNNC) has announced the start of serial production of silicon-28 isotope with record purity — above 99.99%. This is the first time in the country's history that this material has been independently produced on a large scale, marking a significant shift in the global technology race.
Silicon-28 is a silicon isotope lacking nuclear spin, making it an ideal candidate for creating stable qubits in quantum computers. Unlike natural silicon, which contains impurities of the silicon-29 isotope that create magnetic interference, ultra-pure silicon-28 significantly reduces noise levels and increases qubit coherence time. This is critical for scaling quantum systems that could potentially crack modern cryptographic algorithms.
For the crypto industry, this step has dual significance. On one hand, progress in quantum computing accelerates the emergence of threats to RSA and ECDSA — the foundations of blockchain security. On the other hand, China, already dominant in traditional semiconductor production, gains a strategic advantage in developing quantum chips. If Beijing can establish cheap and mass production of silicon-28, it could lead to commercially available quantum processors sooner than expected.
For now, the cryptocurrency market is not reacting directly to this news, but analysts should mark the date: the transition from laboratory samples to industrial production is a signal that the quantum era is approaching faster than many anticipate. Investors in post-quantum cryptography and projects focused on quantum resilience should closely monitor developments.
My comment: Mass production of silicon-28 is not just a technological record but a clear indicator that China is betting on quantum supremacy. For the crypto community, this means the window for transitioning to post-quantum algorithms is narrowing. The market needs to prepare for a paradigm shift within the next 5–7 years.
