For over 100 years now, quantum mechanics has rattled the cage of everything we’ve believed we know about physics. Is everything just made of wiggles and waves if you look close enough? How far can ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, creating a single particle of light that behaves as if it occupies 37 distinct ...

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 ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum dimensions at the same time, and they can make it do the trick on demand. The result ...

Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit ...

Convention has it that quantum mechanics and thermodynamics cannot be true simultaneously – so say scientists at the University of Twente (“UT”), The Netherlands. But now, in a new journal paper, UT ...

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a ...

Physicists from the University of Basel have observed the quantum mechanical Einstein-Podolsky-Rosen paradox in a system of several hundred interacting atoms for the first time. The phenomenon dates ...
