China launches mass production of ultra-pure silicon-28: a breakthrough for quantum computing
China National Nuclear Corporation has officially announced the start of serial production of silicon-28 with an isotopic purity exceeding 99.99%. This event marks the first time in the country's history that this critically important material has been independently produced on a large scale.
Silicon-28 is an isotope that plays a key role in the architecture of silicon quantum computers. Its unique property is the ability to significantly reduce the level of magnetic interference, which directly affects the stability of qubits—the fundamental units of quantum computing. Standard natural silicon contains an impurity of the isotope silicon-29, which creates unwanted noise that destroys quantum states. Removing this impurity to a level of 99.99% or higher allows the creation of qubits with unprecedentedly long coherence times.
Strategic Importance for the Semiconductor Industry
China's achievement in silicon isotope enrichment is directly relevant not only to quantum technologies but also to the broader context of the global semiconductor race. Control over the production of ultra-pure silicon-28 gives Beijing leverage in the supply chain of materials for the next generation of computing. Previously, a monopoly on such technologies belonged only to a few Western laboratories and companies, creating dependence for Asian chip manufacturers.
From my point of view, this step is a clear signal: China intends not just to catch up with leaders in the field of quantum computing, but to form its own raw material base. Given that quantum computers are capable, in the future, of breaking many modern cryptographic algorithms (including those underlying blockchain security), control over the production of silicon-28 becomes a matter not only of technological sovereignty but also of national security. For the crypto industry, this is an additional reminder of the need for an accelerated transition to post-quantum cryptography.
Analytical Summary: The launch of mass production of silicon-28 in China accelerates the commercialization of silicon quantum processors. In the next 3-5 years, we may see a significant reduction in cost and scaling of such systems, which will put direct pressure on traditional security models in blockchain and require proactive adaptation from developers.
