When a beam of light passes through a cloud of atoms, photons (particles of light) sometimes appear to spend a negative amount of time there, with light seeming to exit the cloud before it even enters ...

My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The ...

Legendary experiments in 'cat-turning' from the 1850s can teach us about will, control and goal-seeking behaviour Cats are ...

The first time I went under the knife, I remember the anesthesiologist asking me to count backward. “Ten, nine, eight…” and then it all went black. The next thing I knew, three hours had passed, yet ...

Add Yahoo as a preferred source to see more of our stories on Google. Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the ...

Reality is stranger than anything you can imagine — and quantum physics is the proof. At the subatomic scale, particles vanish through solid walls, exist in two places at once, and communicate ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

Richard Feynman, one of the greatest physicists of the 20th century, once said something that should either comfort or terrify you: “Nobody understands quantum mechanics.” This wasn’t a confession of ...
