| Fig.5 (Color online) The $y$ axis is the lower bound of the Rényi entropy entanglement $E^\beta_{2}(|\psi\rangle_{A|BC})$. The purple line represents the value of $E^\beta_2(|\psi\rangle_{A|BC})$, the red (green resp. yellow) line represents the lower bound from our result for $k=0.5$ ($k=0.7$ resp. $k=0.9$), and the blue line represents the lower bound from the result (55) in Ref.[ |
