Abstract:We study the behaviour of two different measures of the complexity of
multipartite correlation patterns, weaving and neural complexity, for symmetric
quantum states. Weaving is the weighted sum of genuine multipartite
correlations of any order, where the weights are proportional to the
correlation order. The neural complexity, originally introduced to characterize
correlation patterns in classical neural networks, is here extended to the
quantum scenario. We derive closed formulas of the two quantities for GHZ…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
