QUANTUM PHYSICS

Entanglement spread is bounded by area

Nature Physics volume 18, pages 1278–1279 (2022)Cite this article

Subjects

Limits on the quantum entanglement entropy in one dimension have been a key factor in understanding the physics of many-body systems. A bound that applies in any dimension has now been derived for a different measure known as entanglement spread.
