Singapore, 2 October 2026 – Singapore researchers have built what they describe as the world’s most accurate atomic clock, a breakthrough that could strengthen the city-state’s position in quantum science while opening new possibilities in navigation, telecommunications, geodesy and fundamental physics.

Developed by scientists at the Centre for Quantum Technologies at the National University of Singapore, the clock uses a single charged lutetium ion and has achieved an uncertainty of just 1 × 10⁻¹⁹, the lowest reported for any optical atomic clock to date. NUS Newsroom
