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

Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei ...

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 ...

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 ...

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 ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

The demonstrated system achieved short-term fractional frequency stability highlighting the platform’s potential for future chip-scale quantum ...

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 ...

The world’s first nuclear clocks have ticked. A team of physicists has demonstrated a working timekeeping device regulated not by orbiting electrons — as in conventional atomic clocks — but by ...
