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. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.

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 ...

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 ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

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 ...

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.

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Atoms are the world’s most precise timekeepers – so much so that the second is defined as exactly 9 192 631 770 ticks of a caesium-based atomic clock. Commercially-available versions of these ...

The 2022 Breakthrough Prize in Fundamental Physics, one of the set of annual prizes bestowed by the Breakthrough Foundation and backed by Sergey Brin and Mark Zuckerberg among others, has been awarded ...
