Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

Using ultra-cold strontium atoms and powerful laser beams, the team at the University of Science and Technology of China created a clock with stability and uncertainty under 5 quintillionths. The ...

Quantum technologies are reshaping the future of measurement and sensing, and advancements in quantum clocks are at the ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

Recent research published in Physical Review Letters by PTB (Physikalisch-Technische Bundesanstalt) details the development ...

Optical clocks such as the aluminum ion, ytterbium, and strontium clocks have much higher resonance frequencies, high enough to be in the spectrum of light. This allows a much more precise ...

Today, the world’s most precise atomic clocks are the strontium optical lattice clocks created by Jun Ye’s group at JILA in Boulder, Colorado. These are accurate to within a second in the age of the ...

Another significant advancement is the development of a multiplexed optical lattice clock, which allows multiple ensembles of strontium atoms to be interrogated simultaneously. This innovation has ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the ...
