FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

The level of boundary-crossing innovation required to make a nuclear clock 1 serves as an example of how cooperation can exist alongside competition in science. Atomic clocks currently hold the ...

Read the paper: Frequency ratio of the 229mTh nuclear isomeric transition and the 87Sr atomic clock Measuring time has a long history of ingenuity: from counting phases of the Moon to the ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end. According to an announcement from the National ...

The world keeps time with the ticks of atomic clocks, but a new type of clock under development—a nuclear clock—could revolutionize how we measure time and probe fundamental physics.

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 ...

Atomic clocks are very stable over long periods of time, meaning they are reliable for some of the most careful measurements scientists have to make. Ordinary clocks like those in your wristwatch ...

Researchers have developed an optical atomic clock that uses a frequency comb to directly excite a two-photon transition in rubidium-87 atoms. When photons are sent from opposite directions, the ...

One example of this type of sensor is an atomic clock, which goes inside electronic devices to provide the same sort of precision referencing as wireless GPS. They could eliminate the need for the ...
