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 ...

Fraser interviews quantum expert Sean Carroll. Credit: Universe Today To describe that deviation, physicists use a term known as the Eötvös parameter. It explains how closely gravitational mass and ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring minute ...

A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Fuzziness may rule the quantum realm, but it can be manipulated to our advantage. When two black holes spiral inward and collide, they shake the very fabric of space, producing ripples in space-time ...

LIGO is a U.S. science megaproject built to detect ripples in spacetime known as gravitational waves. The ones we can detect are largely created by the mergers of black holes and neutron stars. These ...

A new version of a strange experiment in which a particle’s properties are separated from its body or mass, called the quantum Cheshire Cat, has physicists arguing over whether these disembodied ...

In a paper recently published in the journal Science Advances, scientists from the Vienna Center for Quantum Science and Technology described how they used a “path-entangled quantum interferometer” to ...
