China has launched mass production of silicon-28: a breakthrough for quantum computing
The China National Nuclear Corporation (CNNC) has officially announced the start of mass production of silicon-28, an isotope with a purity exceeding 99.99%. This event marks the first time in the country's history that this material has been independently produced on a large scale, previously available only in laboratory conditions or supplied from abroad.
Silicon-28: The Foundation of Stable Qubits
Silicon-28 is an isotope devoid of nuclear spin, which is critically important for quantum computing. Unlike natural silicon, which contains an impurity of the silicon-29 isotope (about 4.7%) that creates magnetic interference and destabilizes qubits, ultra-pure silicon-28 allows for a sharp reduction in noise levels. This directly increases the stability and coherence time of qubits—a key parameter for creating functional quantum processors.
Geopolitical and Technological Context
This move by Beijing is not just a technical achievement but a strategic maneuver in the global quantum technology race. Previously, Russia was the main supplier of high-purity silicon-28 on the world market, but now China is gaining complete independence in this critical supply chain. Given that quantum computers are capable of breaking modern cryptographic algorithms (including SHA-256, which underpins Bitcoin), control over the production of such material gives Beijing a tangible advantage in creating post-quantum security systems.
Impact on the Crypto Industry
Although silicon-28 is not directly related to blockchain, its mass production accelerates the arrival of the quantum computing era. For the crypto community, this is an alarming signal: the faster quantum technologies develop, the sooner the industry will have to adopt post-quantum cryptography. If China can scale production and reduce the cost of silicon-28, we will see an acceleration in the commercialization of quantum processors within the next 5–7 years.
Analytical Summary: The launch of mass production of silicon-28 is not just news from the world of physics, but a direct signal for crypto investors: the time to prepare for the quantum transition is shrinking. I believe that within 3–5 years, we will witness the first practical attacks on existing cryptographic standards, and those blockchain projects that are already integrating post-quantum algorithms will gain a significant competitive advantage.
