Polygamy relations for tripartite and multipartite quantum systems
Abstract
We study the polygamy property for tripartite and multipartite quantum systems. In tripartite system, we build a solution set for polygamy in tripartite system and find a lower bound of the set, which can be a sufficient and necessary condition for any quantum entanglement of assistance Q to be polygamous. In multipartite system, we firstly provide generalized definitions for polygamy in two kind of divisions of n-qubit systems, and then build polygamy inequalities with a polygamy power β, repectively. Moreover, we use right triangle and tetrahedron to explain our polygamy relations according to the new definitions.
