Tighter monogamy relations of multiqubit entanglement in terms of Rényi-α entanglement

Li-Min Gao,Feng-Li Yan,Ting Gao

Figure 2. The y axis is the Rényi-α entanglement of $| \varphi \rangle $ with α = 1.5 and its lower bound. The (red solid) line e represents the Rényi-1.5 entanglement of $| \varphi {\rangle }_{A| {BC}}$ in Example. The (green dashed) line f denotes the lower bound given by inequality (23). The (blue) line g is the lower bound from the result in [9].
