摘要：
We provide strong evidence for the strong monogamy inequality of multiqubit entanglement recently proposed [B. Regula et al., Phys. Rev. Lett. 113, 110501 (2014)]. We consider a large class of multiqubit generalized W-class states and analytically show that the strong monogamy inequality of multiqubit entanglement is saturated by this class of states.
