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 most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Nobel laureate Arthur Schawlow’s advice to “never measure anything but frequency” is a central principle of modern precision metrology and timekeeping. Today’s spectroscopy is advanced enough to teach ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

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 ...

Like the teeth of a comb, a microcomb consists of a spectrum of evenly distributed light frequencies. Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, ...
