Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

Ultra precise Chinese lattice clock joins international system, challenging decades of US dominance in global timekeeping ...

A Chicago-based group of scientists have once again warned the world is closer than ever to human-made destruction by moving the symbolic “Doomsday Clock” up to 85 seconds to midnight.

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State ...

Time will no longer be imposed upon us by a cesium fountain clock at the National Institute of Standards and Technology,” says experimental philosopher Jonathon Keats, who is leading the initiative in ...

Future Market Insights (FMI) estimates the Atomic Clock Market at USD 651.6 million in 2026 and projects it to reach USD ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...

In the realm of first-world problems, your cheap wall clock doesn’t keep time, so you have to keep setting it. The answer? Of course, you connect it to NTP and synchronize the clock with an ...
