China's Thorium-229 Nuclear Clock Six Times More Stable Than Vienna's
What happened
China's thorium-229 nuclear clock is about six times as stable as Vienna's, according to Nature papers published this week. The two teams—Tsinghua University and Vienna's TU Wien—each built the world's first working nuclear clocks using thorium-229 nuclei embedded in crystals. The Chinese result marks a milestone in precision timekeeping technology, with potential applications in GPS, communications and fundamental physics research.

- SCMP ChinaChina's thorium-229 nuclear clock beats Vienna's on stability, studies show
Initial results from the world's first two working nuclear clocks show China's timepiece is about six times as stable as Vienna's, according to Nature papers published this week. The Chinese team at Tsinghua University and Vienna's TU Wien both used thorium-229 nuclei embedded in crystals to keep time. This marks a milestone in precision timekeeping technology. 研究显示中国钍-229核钟稳定性优于维也纳同类装置 世界首批两个可运行的核钟初步结果显示，中国核钟稳定性约为维也纳核钟的六倍，相关论文本周发表于《自然》。中国团队由北京清华大学领导，维也纳团队为TU Wien。双方均使用嵌入晶体中的钍-229原子核计时。
