Breakthrough could pave the way for next-generation GPS in drones, smartphones and self-driving cars, scientists say.

Home > Extreme New super-accurate atomic clock could be ultra-portable thanks to chilly atoms The smallest atomic clocks are lacking in long-term accuracy, and larger clocks are incredibly expensive.

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 ...

Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...

WASHINGTON — Researchers have 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 ...
