美國商務部修訂對格芯（GlobalFoundries）的《芯片與科學法案》資助協議。

Researchers at the University of Science and Technology of China and the Jinan Quantum Technology Research Institute reported a high‑efficiency, low‑noise quantum frequency conversion from 393 nm (UV) to 1,550 nm (telecom) that enables interfacing trapped‑ion memories with optical fiber. The team led by Pan Jianwei, Zhang Qiang and Zheng Mingyang said the result sets an international record for conversion efficiency and noise in this wavelength range and provides key technology for remote interconnection of trapped‑ion nodes in scalable quantum networks. The findings are published in Physical Review Letters.
