Researchers at Singapore's Centre for Quantum Technologies built a lutetium atomic clock, challenging the old caesium standard. The team achieved a record uncertainty of 1 x 10-19 using lutetium-176 ions. This precision means the clock gains or loses only one second every 300 billion years. Comparing two such clocks yielded an uncertainty of 5.7 x 10-19 over 200 hours. The next goal is miniaturizing this lab-scale prototype for broader applications. π¬
