Quantum physics

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.

A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide.

New calculations suggest physicists may someday discover a fundamental theory of gravity, but it could require a radical new perspective on the universe.

Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.

Physicists have discovered a jewel-shaped geometric object that challenges the notion that space and time are fundamental constituents of nature.

An interview with the Berkeley chemist K. Birgitta Whaley on the promise and challenge of translating quantum biology into practical quantum devices.

New findings suggest that beneath the surface of quantum theory lies a vibrant string theory world where some matter corresponds to black holes in higher dimensions.
