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

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

Measuring the world precisely is much harder than it sounds. At very small scales, ...

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

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

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 ...

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 ...

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

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 ...

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.

Quantum computing is slowly entering the mainstream, as more people discuss the technology and its potential within ...
