Strontium atomic clocks have important applications, ranging from tests of general relativity to searches for possible variations in fundamental constants. But the precision of these clocks has been ...

Scientists from the University of Colorado Boulder have created an atomic clock using lasers and strontium atoms that’s incredibly accurate—only losing one second every 40 billion years.

Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn't lose or gain a ...

The theory was developed by Neils Bohr's great-grandson. The use of a special type of atom could make even the most advanced atomic clocks more precise, scientists believe. If confirmed, this ...

A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) ...

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.

NASA scientists are moving on from typical atomic clocks and using optical light and strontium atoms to build a new future.

New clock just dropped, but it’ll only drop a second every 30 billion years while in operation. That’s right: It’s the most precise, accurate clock yet built. The timekeeping device was ...

"Many recent atomic clocks, ours included ... which highlighted the potential of building precise optical lattice clocks using strontium atoms. "A typical clock has three components: an oscillator ...

The team also compared their UV frequency to the optical frequency of another of the world’s most accurate strontium-based atomic clocks to establish the first “direct frequency link ...

Atomic clocks use these frequencies — specifically ... The aluminum-ion and ytterbium clocks were kept in a lab in Boulder, Colorado. The strontium clock was placed about a mile away in a ...

First, it doesn’t use cesium atoms but strontium instead, which tick an insane 429 trillion times per second. Rather than measuring these ticks using microwaves, this kind of atomic clock uses ...
