Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

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 radical idea that resolves many quantum paradoxes suggests there is no objective view of reality. How can the cosmos be ...

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

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 ...

The original version of this story appeared in Quanta Magazine. Imagine standing on a railway platform watching a trolley go past. A girl on the trolley drops a bright red ball. To her, the ball falls ...

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 ...
