Singapore Researchers Develop Record-Accurate Lutetium Atomic Clock for Precision Timekeeping
Researchers at the National University of Singapore's Centre for Quantum Technologies have developed a lutetium-based optical atomic clock with a record frequency uncertainty of 1×10⁻¹⁹, making it one of the most precise clocks to date. The team created two independent clocks, achieving a comparison uncertainty of 5.7×10⁻¹⁹. This clock's stability across environmental changes and sensitivity to gravitational potential variations could advance precision timekeeping and support scientific fields like geophysics and fundamental physics. Plans include developing a transportable version for broader applications.
