Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the ...

Earth’s rotation has been measured many times over — but never like this. In a first, scientists used entangled quantum particles called photons to reveal the rate at which the globe spins. The feat ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

A discovery that may someday help measure how clouds and earthquakes change Earth’s rotation has come from an experiment that made friction-free helium whistle. A discovery that may someday help ...
