A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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 ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...

Quantum theory is a mind-bending idea, suggesting that, at the subatomic level, particles can exist in multiple states at the same time. Scientists often give the example of physicist Erwin ...

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 ...

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 ...

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 ...

For over a century, quantum mechanics has challenged our established notions of physics. At its core are questions that unsettle our understanding of the universe: when does a quantum particle ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...
