"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local ...

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 ...

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 ...

In a groundbreaking discovery, researchers from Nagoya University in Japan and the Slovak Academy of Sciences have unveiled new insights into the interplay between quantum theory and thermodynamics.

One of the most important paradoxes in physics is Schrödinger's Cat. At the microscopic level, light and particles behave according to quantum mechanics. This allows them to be in two places at once ...

(via Sabine Hossenfelder) Physicists have come up with a new experiment to test the quantum twin paradox using a pair of atoms in a superposition. It's an interesting idea because it could tell us ...

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 ...
