Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought experiment where particles and their antiparticles might exist simultaneously ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

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

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 ...

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

Add Yahoo as a preferred source to see more of our stories on Google. The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions. A ...

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 ...

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

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