Strontium atomic clock accurate to the second -- over 15 billion years. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2015 / 04 / 150421132031.htm ...

The strontium clock's stability -- the extent to which each tick matches the duration of every other tick -- is about the same as NIST's ytterbium atomic clock, another world leader in stability ...

PORTLAND, Ore. — A candidate to be the next-generation atomic clock is based on the heavy metal strontium and uses a laser lattice to suspend super-cooled atoms. The result was a 430-THz time ...

Bothwell et al. 1 and Zheng et al. 2 now report astounding progress in the stability of atomic clocks using ensembles of ultracold strontium atoms. Bothwell and colleagues even managed to measure ...

At LNE-SYRTE, the strontium clock frequency was measured extensively ... to take place in less than a few 100 μs, affecting the atomic populations at an insignificant level of 10 −6.

An atomic clock that sets the time by the teensy oscillations of strontium atoms has gotten so precise and stable that it will neither gain nor lose a second for the next 15 billion years.

The strontium lattice clock sets new standards for precision and stability, only gaining or losing one second about every five billion years. Atomic clock performance can be measured by two key ...

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.

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 ...

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 ...

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 ...
