Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up GPS and the internet, among other things. Now, scientists have built and tested the first p...

These clocks are used by national governments and scientific labs to ensure that their timekeeping is accurate and uniform. Laboratories use atomic clocks to keep highly accurate time. A number of companies also sell clocks which are labeled as "atomic" to consumers. These clocks are actually ...
Atomic clocks use quantum timekeepingNature - the world's best science and medicine on your desktopdoi:10.1038/news.2010.163Zeeya MeraliNature
Because atomic clocks are already more than accurate enough for most practical uses , scientists are not aiming to replace them. Instead, they are more interested in the advantages of having two independent methods for measuring time, as beyond precise timekeeping . nuclear clocks could have broader...

The most accurate mechanical timekeeper is theShortt pendulum clock; it makes use of the movement described above for electric master clock systems. The Shortt pendulum clock consists of two separate clocks, one of which synchronizes the other. The timekeeping element is a pendulum that swings fr...
Atomic clocks are designed to measure the precise length of asecond, the base unit of modern timekeeping. The International System of Units (SI) defines the second as the time it takes a caesium-133 atom in a precisely defined state to oscillate exactly: ...
’s some really interesting physics going on because you have these interacting dipoles,” Milner elaborates, “So people, such as Ross Hutson, have ideas for even potentially using these dipole-dipole interactions for spin squeezing [a type of quantum entanglement] to make even better clocks.”...
While their nuclear clock is still a work in progress, once realized it could transform not only timekeeping but also the study of physics, even affecting how scientists investigate the fabric of the universe. The prototype is not yet as accurate as an atomic clock, but future versions are ex...
