University of Calgary mathematician Gilad Gour discovered a simple factorization law for multipartite entanglement evolution of a composite quantum system with one subsystem undergoing an arbitrary physical process. Gour introduced the "entanglement resilience factor", which uniquely determines the multipartite entanglement decay rate. Well known bipartite entanglement evolution emerges as a special case, and this theory also readily reveals whether a permuted version of a given entangled state can be obtained by local operations.
