Quantum physics

The new work promises to give researchers a better grip on the core mystery of quantum mechanics.

The Frauchiger-Renner thought experiment has shaken up the world of quantum foundations.

On November 16, 2018, more than 200 readers joined writers and editors from Quanta Magazine for a wide-ranging panel discussion that examined the newest ideas in fundamental physics, biology and mathematics research.

Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.

The idea that the universe splits into multiple realities with every measurement has become an increasingly popular proposed solution to the mysteries of quantum mechanics. But this “many-worlds interpretation” is incoherent, Philip Ball argues in this adapted excerpt from his new book Beyond Weird.

Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists a single, concrete reality.

A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.

Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.

A quickly closed loophole has proved that the “great smoky dragon” of quantum mechanics may forever elude capture.
