Quantum physics

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.

New tools may reveal how quantum information builds the structure of space.

A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.

A quantum computing pioneer explains why the near future of quantum computation may lie in simulators, not general-purpose quantum machines.
