“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means is up for interpretation.

Winners opened the way to powerful new quantum technologies Findings enabled work on quantum computers, encryption Winners' research is based on 'mind-boggling' insight Zeilinger 'shocked but very ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...

Researchers from the University of Waterloo's Faculty of Science and the Institute for Quantum Computing (IQC) are ...

The double-slit experiment is the best demonstration of quantum weirdness, in which electrons simultaneously act like particles and waves and seemingly violate basic laws of physics. Now we’re trying ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...
