Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

He added that the team learned the behaviour of their system in 15 minutes. A comparable classical method would take around 20 million years. The experiment took place in the basement labs at DTU ...

Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

When hundreds of physicists gathered on a Zoom call in late February to discuss their experiment’s results, none of them knew what they had found. Like doctors in a clinical trial, the researchers at ...

A U.S. research lab has announced one of the most precise measurements ever of how a subatomic particle behaves, teeing up a showdown that could either vindicate one of science’s most powerful ...
