Quantum physics

How quantum entanglement connects with the “many worlds” of quantum theory.

The cognitive scientist Donald Hoffman believes that evolution and quantum mechanics conspire to make objective reality an illusion.

In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.

Three computer scientists have solved a problem central to a dozen far-flung mathematical fields.

Einstein refused to believe in the inherent unpredictability of the world. Is the subatomic world insane, or just subtle?

Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.

Quantum theorist Christopher Fuchs explains how to solve the paradoxes of quantum mechanics. His price: physics gets personal.

Imagine the fabric of space-time peeled back layer by layer.
