The trial is the first time that DSTL has tested a UK-built optical atomic clock outside of a laboratory, offering a new ...

There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS ...

Scientists in the United States have made significant achievements for the development of a practical nuclear clock. A team of researchers, led by JILA and NIST Fellow and University of Colorado ...

That big grandfather clock ... atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the clock up to it. Now, we ...

A team of Chinese researchers has reportedly developed the most precise portable atomic clock ever. Small and rigid by design, this new timepiece can be easily transported to war zones ...

Chinese researchers have developed the world's smallest and most robust atomic clock that can survive the rigors of war.

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks ...

However, building such a clock has posed major challenges—thorium-229, one of the isotopes used in nuclear clocks, is rare, radioactive, and extremely costly to acquire in the substantial ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even ...

Solid-state clock Illustration of how thorium atoms are vaporized (bottom) and then deposited in a thin film on the substrate’s surface (middle). This film could form the basis for a nuclear clock ...

Abstract: In order to eliminate the light shifts and to increase the stability of gas-cell atomic clocks using optical pumping of the alkali atoms, the detection of a microwave pulse-induced coherent ...
