Quantum physics

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.

Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.

Three groups of experimentalists have independently observed a strange state of matter that forms from three particles of any type and at any scale, from practically infinitesimal to infinite.

A scientist at Bell Labs has started construction of a topological qubit, which could be the building block of a robust, scalable quantum computer.
