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

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

Figure 1. The y axis is the Rényi-α entanglement of $| \varphi \rangle $ with α = 2 and its lower bound. The (red solid) line a represents the Rényi-2 entanglement of $| \varphi {\rangle }_{A| {BC}}$ in Example. The (green dashed) line b denotes the lower bound given by inequality (21). The (blue) line c expresses the lower bound from the result in [28, 29] when α = 2. The (black) line d is the lower bound from the result in [9].
