Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

Researchers at Wuhan University (WHU) in China have produced a commercially manufacturable atomic clock less than one-seventh ...

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 ...

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

The device, which traps thousands of atoms to keep time, is "pushing the boundaries of what's possible with timekeeping." Reading time 2 minutes New clock just dropped, but it’ll only drop a second ...
