An international team built a quantum interferometer, split a single rubidium atom into two simultaneous paths — one falling ...

Physicists have measured, for the first time, how gravity affects the quantum wave of a single falling atom, and the result ...

Physicists split an atomic wave between free fall and a stationary path, revealing a quantum phase predicted nearly a century ago.

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to ...

Scientists measured a predicted quantum phase in freely falling rubidium atoms, finding results consistent with Einstein's ...

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

A new experiment using ultracold rubidium atoms found that a quantum object in free fall behaves consistently with Einstein's ...

Physicists observed a quantum state change in ultracold atoms. This change matched Einstein's equivalence principle for a ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

The double-slit experiment is perhaps the most iconic demonstration in quantum mechanics: showing how a single particle’s ...

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 ...

An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result ...
