Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping. For over a ...

Researchers in the Neutral Atom Optical Clocks Group at the National Institute of Standards and Technology (NIST), University of Colorado and Pennsylvania State University recently devised a new ...

The challenge of creating the world’s most precise clock is that that even the slightest deviations limit the precision. Atomic clocks, which rely on the coherent evolution of atomic states, are the ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

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 ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

In popular culture, lasers are often portrayed as portable blasters that superheat whatever they hit. Some lasers do deliver tremendous amounts of energy in reality, but for scientists and engineers, ...

Researchers at the Ye Lab at JILA (the National Institute of Standards and Technology and the University of Colorado Boulder) and University of Delaware recently created a highly precise optical ...
