Chinese scientists create clock so precise it could redefine second - Optical clock measures time using light emitted by electrons transitioning between energy levels ...

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

(Adam Gault/Photographer's Choice RF/Getty Images) Researchers in China have created one of the most precise clocks ever made ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...

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 ...

Physicists are quietly rewriting one of the most basic units in science, using a new generation of optical clocks that can keep time so precisely they barely lose a beat over the age of the universe.

Researchers from six countries conducted the largest coordinated comparison of optical clocks to date. The measurements amount to the largest coordinated comparison of optical clocks to date, and ...
