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 ...

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

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...

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

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 ...

As explained in a mailing list post by Jeffrey Sherman, a NIST supervisory physicist who maintains the institute’s atomic clocks, “The atomic ensemble time scale at our Boulder campus has failed due ...

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 ...

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.
