An international team of researchers has demonstrated that the equivalence principle, a cornerstone of Einstein’s theory of ...

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

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 ...

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

Physicists including Roger Penrose observed gravity’s effect on a falling quantum object for the first time, confirming ...

Physicists have directly observed gravity's effect on a quantum object, supporting Einstein's theory and advancing the quest ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...

Quantum coherence and decoherence are fundamental indications of how well a system of quantum objects -- atoms or other quantum particles -- maintains its relationships and how reliably the ongoing ...

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 ...
