Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In A Nutshell The world’s most precise clocks are changing how we understand ...

Add Yahoo as a preferred source to see more of our stories on Google. Close up of pink-colored laser beam inside lab instrument. Now, physicists at the US National Institute of Standards and ...

An Arizona-based company has launched its next generation of low-noise Chip-Scale Atomic Clock (CSAC). Microchip's model SA65-LN is designed to operate in a wider temperature range, enabling low-phase ...

Researchers at the UK’s National Physical Laboratory (NPL) have created a tiny atomic fountain ...

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

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 ...

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
