Rubidium Atomic Frequency Standard to be tested in orbit as part of efforts to develop regional positioning and timing system ...

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock—ticking at high "optical" frequencies—that is much ...

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 ...

A new type of miniature atomic clock could provide better timing over the span of weeks and months compared with current systems. Researchers at the National Institute of Standards and Technology ...

A matchbox sized atomic clock could be used to build more accurate automated aircraft navigation systems, its US military creators say. Scientists at the Office of Naval Research have developed a ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...
