Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

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 ...

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 ...
