More accurate strontium-based atomic clocks are possible – and accurate to one second every 40 billion years – by emitting radiation in the visible, rather than microwave, spectrum.

Entangled clocks . In their new atomic clock, Vuletic and his colleagues entangle around 350 atoms of ytterbium, which oscillates at the same very high frequency as visible light, meaning any one ...

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

Correction: A previous version of this story mischaracterized the accuracy of the researchers’ nuclear clock prototype in relation to atomic clocks. The story has also been updated to clarify ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

That's why atomic physicists at NASA want to build a more precise, more autonomous atomic clock. Sponsor Message The team hopes a prototype will be ready by late 2025.

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end. According to an announcement from the National ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

This reliable oscillation became the basis of the first atomic clocks developed in the 1940s and 1950s, and in 1967 the international organization that oversees standards for weights and measures ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...
