U.S. physicists have made a clock so accurate it will neither gain nor lose even a second in more than 200 million years, a finding sure to please even the most punctually minded. The clock, described ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

The quantum clock design proposed by this team of researchers challenges the long-held assumption that increasing the precision of time-keeping devices comes at a cost, namely an increase in energy ...

Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out ...

Tick tock: Artist's impression of a quantum clock. (Courtesy: Alexander Rommel/TU Wien) The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the ...

Stochastic watch: The clock in the experiment consists of a pair of quantum dots coupled by a thin tunnelling barrier. The clock “ticks” whenever an electron tunnels from one side of the system to the ...

For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum clocks, in particular, have pushed the boundaries by using the strange ...
