General Monogamy of Tsallis $q$-Entropy Entanglement in Multiqubit Systems
Abstract
In this paper, we study the monogamy inequality of Tsallis-q entropy entanglement. We first provide an analytic formula of Tsallis-q entropy entanglement in two-qubit systems for The analytic formula of Tsallis-q entropy entanglement in system is also obtained and we show that Tsallis-q entropy entanglement satisfies a set of hierarchical monogamy equalities. Furthermore, we prove the squared Tsallis-q entropy entanglement follows a general inequality in the qubit systems. Based on the monogamy relations, a set of multipartite entanglement indicators is constructed, which can detect all genuine multiqubit entangled states even in the case of -tangle vanishes. Moreover, we study some examples in multipartite higher-dimensional system for the monogamy inequalities.
