A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...
A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.
Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in ...
Researchers from Los Angeles, Munich, and Mainz open new avenues for nucleus-based quantum technologies A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian ...
(THE CONVERSATION) Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a ...
Using ultraprecise atomic clocks, along with technologies developed from trapped-ion quantum computing, scientists are ...
Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...
To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.
