Chinese Nuclear Clock Demonstrates Greater Stability Than Vienna's in Timekeeping Race
According to the South China Morning Post, initial findings from the world's first two functional nuclear clocks suggest that China's timepiece exhibits approximately six times the stability of the clock in Vienna, as detailed in recent publications in the journal Nature.

The South China Morning Post reports that initial outcomes from the world's first two operational nuclear clocks indicate that the clock developed by the Chinese team is about six times more stable than the one located in Vienna, based on papers released this week in the journal Nature.
Both the Chinese team, which is led by Tsinghua University in Beijing, and researchers at TU Wien in Vienna utilized thorium-229 nuclei embedded within crystals to maintain time. This method relies on the consistent rhythm of the atom's core, differing from traditional atomic clocks that measure the electrons orbiting the nucleus.
Thorsten Schumm, a member of the European research group, stated that the development of these radical new devices by the two teams independently, which was reported by Nature in June, has initiated what he described as a "fierce but friendly global competition."
Furthermore, the Beijing scientists presented evidence demonstrating that two crystals, which were grown independently, maintained synchronized time, suggesting that such clocks possess reliable reproducibility. Concurrently, the Vienna team employed its clock in an effort to search for dark matter, though this search did not yield any findings.
