This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with the improved stability of multi-ion operation. The new atomic species is ...

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 ...

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 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 ...

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

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
