Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

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, making it ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

A standard atomic clock takes a beam of atoms that ... will be more precise than the same ruler with 4 marks. While a cesium clock may be off one second in 100 million years, the optical clocks ...

With access to a 10-MHz timebase from a cesium fountain 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 ...

Researchers have developed a new approach in optical atomic clocks that brings forth a major goal in science: the ...

If you buy through a BGR link, we may earn an affiliate commission, helping support our expert product labs. Scientists from MIT have developed what they believe is the most accurate atomic clock ...

Standing 1.5 metres (4.9 feet) tall and roughly the size of a single-door refrigerator, the caesium atomic fountain clock can be loaded onto a military truck and, after enduring long-distance ...

Revolutionary technology is breaking out of the lab. The British government has announced that it is deploying a top-secret ...

An atomic clock is known to be the most accurate measurement ... which is the 9,192,631,770 times per second electrons transition to a new level in cesium atoms. See real-time clock and atom.

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the ...
