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

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

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 ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...

Physicists at the National Institute of Standards and Technology (NIST) have "entangled" or linked together the properties of up to 219 beryllium ions (charged atoms) to create a quantum simulator.

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 ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...
