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

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

In advance of hurricane force winds moving into Colorado earlier this week, Xcel Energy preemptively shut off power to protect areas of the state from extreme fire danger. But due to the outage, time ...

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 ...

How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

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 ...

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 ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

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 ...

NTP is one of the most interesting and important, but all to forgotten, protocols that makes the internet tick. Accurate ...
