Tighter monogamy relations of multiqubit entanglement in terms of Rényi-$\alpha$ entanglement

Abstract

We present a class of tight monogamy relations in terms of Rényi-$\alpha$ entanglement, which are tighter than the monogamy relations of multiqubit entanglement just based on the power of the Rényi-$\alpha$ entanglement for $\alpha \ge 2$ and the power $\eta >1$. For $2>\alpha \ge \frac{\sqrt{7}-1}{2}$ and the power $\eta >2$, we establish a class of tight monogamy relations of multiqubit entanglement with larger lower bounds than the existing monogamy relations of multiqubit entanglement.
