The world’s network of atomic clocks is already mind-bogglingly accurate. They also underpin a slew of modern necessities, from GPS to internet communication. Atomic clocks work by tuning a laser to ...

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 ...

Two independent teams have locked lasers to the nucleus of thorium-229 and kept time with it, one clock running untouched for ...

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...

By measuring the squishing and unsquishing of thorium-229 nuclei, two teams created a new type of clock that could someday beat the precision of atomic clocks.

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 ...

Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time—and with record-setting ...
