Multipartite entanglement
arXiv:2409.04566
Abstract
In this contribution we present a concise introduction to quantum entanglement in multipartite systems. After a brief comparison between bipartite systems and the simplest non-trivial multipartite scenario involving three parties, we review mathematically rigorous definitions of separability and entanglement between several subsystems, as well as their transformations and measures.
Multipartite Entanglement will be a chapter in Encyclopedia of Mathematical Physics 2nd edition
