China launches mass production of silicon-28: a breakthrough for quantum computing
The China National Nuclear Corporation (CNNC) has officially announced the start of industrial production of silicon-28, an isotope critical for creating stable quantum processors. The declared isotopic purity of the material exceeds 99.99%, making it the country's first product of this level produced on an industrial scale.
Why is silicon-28 important for the crypto industry?
Silicon-28 is not just a raw material for microelectronics. In silicon-based quantum computers, this isotope reduces magnetic interference that destroys the quantum states of qubits. The higher the purity of the isotope, the longer the qubit maintains coherence, meaning quantum algorithms—including those that crack modern cryptographic schemes—can be more complex and reliable.
The launch of mass production in China means that Beijing is betting on quantum supremacy. For crypto analysts, this is a signal: traditional asymmetric cryptography (RSA, ECDSA) may be under threat sooner than expected. The material base for quantum machines is no longer a laboratory curiosity but an industrial standard.
My assessment: China's breakthrough in silicon-28 production is not just a tech news item but a strategic move. If quantum computers based on this material become commercially available within the next 5–7 years, the crypto community will have to accelerate the transition to post-quantum algorithms. Ignoring this trend means risking asset security.
