题目:Tighter Monogamy Relations for Concurrence and Negativity in Multiqubit Systems

作者:费少明  教授(其他)

简介:The entanglement in multipartite quantum system is hard to characterize and quantify,although it has been intensively studied in bipartite systems. The monogamy of entanglement, as a special property of multipartite systems, shows the distribution of entanglement in the system.In this paper, we investigate the monogamy relations for multi-qubit systems. By using two entangled measures, namely the concurrence C and the negativity Nc, we establish tighter monogamy inequalities for their a-th power than those in Jin (Phys. Rev. A 2018, 97, 032336). We also illustrate the tightness of our results for some classes of quantum states.
