#China has achieved a breakthrough in the development of a critical material used in silicon-based quantum chips that will bolster frontier science and technology, the China National Nuclear Corporation (CNNC) announced.

China's nuclear engineers sorted silicon like beans and cracked a quantum computing supply bottleneck — which is either a charming way to describe isotope separation or the most accurate. The Research Institute of Physical and Chemical Engineering of Nuclear Industry, part of the China National Nuclear Corporation, has achieved mass production of silicon-28 at purity above 99.99%. The method is physical rather than chemical: silicon atoms exist in nature as three isotopes, and the separation process diverts silicon-28 to one stream while silicon-29 and silicon-30 go to the other. Institute head Jiang Hongmin described it as sorting beans. The process is scalable by design. Silicon-28 is the substrate material for silicon-based quantum chips — the qubit architecture considered most viable for large-scale quantum computing because it is compatible with existing semiconductor fabrication lines. Purity matters because stray isotopes introduce nuclear spin noise that degrades qubit coherence. Until now, isotope-enriched silicon at this grade was scarce, sourced from a small number of foreign suppliers. China's domestic production capability removes that dependency. The same research team has produced 26 stable isotopes across 12 elements, including molybdenum, tellurium, and nickel. Chinese Academy of Sciences academician Yu Dapeng said the achievement clears the path for large-scale qubit research in China. The isotope portfolio spans quantum computing, high-precision navigation, and metrology — the measurement standards that underpin advanced manufacturing. My take — nuclear infrastructure is the upstream answer to semiconductor sanctions. US export controls targeted the downstream: chips, equipment, software. China's response has been methodical work on upstream materials that the controls never named because no one expected industrial-scale isotope separation to move this fast. The CNNC institute doing this work sits inside the same nuclear complex that handles enrichment for other purposes — the capability transfer is not incidental. Sanctioning a country's access to finished technology and watching it build the feedstock layer is a proven strategy in response to empire's attempts to sanctions all who threaten its hegemony.

【中国がシリコン系量子チップの重要材料開発で大きな進展】中国核工業集団（CNNC）が6月15日明らかにしたところによると、中国の研究者は安定同位体の濃縮で重要な進展を遂げ、存在比が99.99%を超えるシリコン28同位体の自主量産に初めて成功し、製品の重要指標は国際的な先進レベルに達したとのことです。 シリコンは非金属元素であり、天然のシリコンにはシリコン28、シリコン29、シリコン30の3種類の安定同位体が含まれています。うちシリコン28が92.2%を占めており、この同位体は量子計算における環境ノイズの干渉を大幅に低減することができ、「世界で最も純度の高いシリコン」と呼ばれています。一方、天然シリコンのもう一つの安定同位体であるシリコン29は量子計算に干渉を引き起こします。このため、干渉を最小限に抑えるには、シリコン28の存在比を92.2%から99.99%以上に高める必要があります。 中国核工業集団理化学工程研究院の姜宏民院長によると、シリコン28を精製するには、シリコン29を物質反応によりシリコン28に変えるのではなく、豆をふるいに掛けるように3種類の同位体を分離する必要があり、シリコン28を一方に集め、シリコン29とシリコン30をもう一方に分離することで、総量は変わらないものの各成分の存在比が変わるとのことです。 超高純度のシリコン28は量子計算のほか、先端半導体プロセスやハイエンドナビゲーション、計量標準など最先端分野でも幅広い展開が見込まれています。japanese.cgtn.com/2026/06/16…

China mencapai terobosan dalam pengembangan material penting yang digunakan dalam cip kuantum berbasis silikon, yang akan memperkuat ilmu pengetahuan dan teknologi mutakhir. Demikian diumumkan China National Nuclear Corporation (CNNC) pada Senin (15/6) tinyurl.com/3u7ybsfa

China schließt eine strategische Technologielücke. Im Wettlauf um Quantencomputer verschärft sich der globale Wettbewerb weiter. #China #Quantencomputer #Technologie #CNNC Durchbruch: Der staatliche chinesische Atomkonzern CNNC meldete am 15. Juni 2026 die Massenproduktion von Silizium 28 mit einer Reinheit von über 99,99 Prozent. Das Material gilt als entscheidender Rohstoff für siliziumbasierte Quantencomputer und war bislang nur über wenige internationale Lieferketten verfügbar. Wettbewerb: China will damit einen wichtigen Engpass beseitigen und seine technologische Unabhängigkeit stärken. Laut CNNC ermöglicht Silizium 28 stabilere Qubits für Quantencomputer. Die Ankündigung erfolgt in einer Phase zunehmender Technologiekonflikte zwischen China und den USA. Der technologische Abstand zwischen den führenden Wirtschaftsräumen wird künftig immer stärker von der Kontrolle strategischer Schlüsseltechnologien abhängen. Vielen Dank für den wichtigen Hinweis!
