How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
Universal Quantum Phenomenon Found in Strange Metals
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.
‘Quantum Atmospheres’ May Reveal Secrets of Matter
A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.
Dark Energy May Be Incompatible With String Theory
A controversial new paper argues that universes with dark energy profiles like ours do not exist in the “landscape” of universes allowed by string theory.
