science 🔬 Singapore built world's most accurate atomic clock ⏱️
Scientists at Singapore’s Centre for Quantum Technologies developed a lutetium-ion atomic clock boasting record accuracy. This team compared two single-ion lutetium clocks over 200 hours, finding they differed by only about one second over 55 billion years. The clock's stability against temperature and magnetic fields supports fundamental physics studies. This breakthrough also contributes data towards a possible redefinition of the second after 2030. Next, the team plans to miniaturize the lab-scale clock for transportable systems.
