【摘要】 <正>We prove that the squared Rényi-aentanglement(SRαE),which is the generalization of entanglement of formation,obeys a general monogamy inequality in an arbitrary N-qubit mixed state.Furthermore,for a class of Rényi-aentanglement,we prove that the monogamy relations of the SRαE have a hierarchical structure when the N-qubit system is divided into k parties.As a更多还原
