We present classes of monogamy inequalities related to the αth (α ⩾ 1) power of the entanglement measure based on the unified-(q, s) entropy, and polygamy inequalities related to the βth (0 ⩽ β ⩽ 1) power of the unified-(q, s) entanglement of assistance by using Hamming weight. We show that these monogamy and polygamy inequalities are tighter than the existing ones. Detailed examples are given for illustrating the advantages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
