中国科学技术大学研究人员开发出九章4.0光量子计算原型机，可操控3050个光子，创下新纪录。
中国科学技术大学宣布推出九章4.0原型机。该设备使用1024个压缩态输入和8176模干涉网络。
该原型机在25微秒内完成高斯玻色采样任务。据估计，世界最强超级计算机El Capitan完成同样计算需超过10^42年。
研究团队由潘建伟领导，与多家中国研究机构合作。成果已于本周三发表在《自然》杂志上。
与之前的九章3系统相比，新设备的光子处理能力提升超过十倍。

China's Zhengzhou core node has doubled its chips to 60,000 from 30,000 since early February trials, becoming the nation's most powerful scientific intelligent computing infrastructure, CCTV reported.
Researchers have developed a mathematical approach showing quantum computers could efficiently process large datasets for AI tasks. By loading data in batches like streaming, the method avoids massive memory needs. A machine with just 60 logical qubits could outperform classical systems by decade's end.

Qunnect, a Brooklyn-based company, has created technology to share quantum-entangled photons for secure communication networks. The firm recently achieved entanglement swapping over 17.6 kilometers of fiber-optic cables between Brooklyn and Manhattan. This advancement supports the development of an unhackable quantum internet.
