World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

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 ...

Optical atomic clock technology has reached space for the first time after Australian startup QuantX Labs confirmed a Nobel ...

A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift matters because this clock does more than keep time. It can also watch for ...

For the first time, scientists used an atomic nucleus as a clock. The world’s most precise timepieces are made using atoms, specifically their electrons. But clocks based on atomic nuclei — protons ...

Scientists have built the first working nuclear clock, which uses the vibrations of atomic nuclei to keep time. Nuclear clocks have been sought after for more than two decades and could eventually ...

The best timekeepers today—atomic clocks—work off the quantum vibrations of an atom, specifically its electrons. But physicists have long dreamt of even better clocks that run on atomic nuclei, which ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...
