This atomic clock is so precise it can detect how gravity changes time. Scientists now want to take it outside the lab and measure tiny shifts across Earth

Economic Times - Sep 24, 2026

Researchers at Singapore's Centre for Quantum Technologies have developed a highly accurate lutetium-based atomic clock. This clock has a reported frequency uncertainty of 1 × 10⁻¹⁹, making it one of the most precise clocks available. The team successfully demonstrated the clock’s sensitivity to minute differences in gravitational potential. Future plans involve creating a transportable version of the clock for various scientific applications.
