Scientists have built the world's most accurate atomic clock – and it's so precise it could redefine the second. Experts at Singapore's Centre for Quantum Technologies (CQT) have developed a device ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...
