Scientists are using atomic clocks to investigate some of the universe's greatest mysteries, including the nature of dark matter, in a laboratory. In the process, they say they're bringing cosmology ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

(CNN) — Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision, ...

As well as being useful for creating an optical ion clock, this multi-ion capability could also be exploited to create quantum-computing architectures based on multiple trapped ions. And because the ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...
