Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium ...

What we’re able to do is divide the same length of time into smaller and smaller units, Adam Kaufman described, speaking to how entanglement sharpens the tick of optical atomic clocks. That one line ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

The Department of Defense has awarded quantum technology firm Infleqtion an $11 million contract to help it speed up the development of its atomic timing technology. Atomic clocks are one of the most ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

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 ...
