Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, you expect objects to follow straightforward rules. A ball thrown into the ...

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 ...

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 ...

Let me tell you about my book "Fields and Their Quanta: Making Sense of Quantum Foundations," published last year by Springer. It's technical, but I'll describe it in English. Scientists agree the ...

Viruses exist at the boundary between living and non-living matter, while skin is a living interface between physics and ...

Classical and quantum mechanics don’t really get along as the science of the subatomic can get, well, weird. Take, for instance, quantum entanglement, which says that the state of one particle can be ...
