Multipartite concurrence of W-class states based on sub-partite quantum systems
Wei Chen, Yanmin Yang, Shao-Ming Fei +2
We study the concurrence for arbitrary N-partite W-class states based on the (N-1)-partite partitions of subsystems by taking account to the structures of W-class states. By using…
Tighter monogamy relations for the Tsallis-q and Rényi- entanglement in multiqubit systems
Rongxia Qi, Yanmin Yang, Jialing Zhang +1
Monogamy relations characterize the distributions of quantum entanglement in multipartite systems. In this work, we present some tighter monogamy relations in terms of the power of…
Tighter Monogamy Relations in Multi-Qubit Systems
Yudie Gu, Yanmin Yang, Jialing Zhang +1
In this paper, we present some monogamy relations of multiqubit quantum entanglement in terms of the βth power of concurrence, entanglement of formation and convex-roof extended ne…
General Monogamy Relations for Multiqubit W-class States in terms of negativity and squared Rényi- entanglement
Yanying Liang, Xiufang Feng, Wei Chen
For multipartite entangled states, entanglement monogamy is an important property. We investigate the monogamy relations for multiqubit generalized W-class states. We present new a…
Generalized monogamy inequalities of convex-roof extended negativity in -qubit systems
Yanmin Yang, Wei Chen, Gang Li +1
In this paper, we present some generalized monogamy inequalities based on negativity and convex-roof extended negativity (CREN). These monogamy relations are satisfied by the negat…
