Quantum physics

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.

Newly discovered particles are forcing physicists to extend their simple picture of subatomic interactions or replace it with a more nuanced understanding.

Physicists have begun to explore the idea that mass and length may not be fundamental properties of nature. The hypothesis could help to avoid the conclusion that our world is just a weird bubble in an endlessly foaming multiverse.
