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

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

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.

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 ...

Secretary General of the Royal Swedish Academy of Sciences Hans Ellegren, centre, Eva Olsson, left and Thors Hans Hansson, members of the Nobel Committee for Physics announce the winner of the 2022 ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American This was supposed to be an action-packed ...

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 ...
