In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

This article is part of a package in collaboration with Forbes on time capsules, preserving information and communicating with the future. Read more from the report. Yet according to physics, ...

Breaking the time asymmetry remains a fundamental yet tantalizing scientific challenge. At the macroscopic level the quest has so far turned out to be fruitless, but on the other hand in the subatomic ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions. A study takes this GHZ paradox to new heights to see just how ...

Physicists have pushed one of the strangest ideas in science into new territory, holding tiny clumps of metal in a quantum limbo that recalls Schrödinger’s famous cat. Instead of a single atom or ...

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

Quantum mechanics, the theory that governs the subatomic world, rests on a persistent paradox. It describes particles that ...
