China has achieved mass production of the high-purity silicon-28 isotope, a critical component for quantum computing. This breakthrough by the China National Nuclear Corporation (CNNC) marks China's first independent large-scale production of the material, addressing a significant gap in its quantum technology supply chain. Previously, this isotope was primarily sourced from Russia, Europe, and US-linked supply chains. The silicon-28 isotope is essential for creating stable qubits by minimizing magnetic interference, a key challenge in building functional quantum computers. AI
