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

@article{Gao2020TighterMR, title={Tighter monogamy relations of multiqubit entanglement in terms of R{\'e}nyi-$\alpha$ entanglement}, author={Limin Gao and Fengli Yan and Ting Gao}, journal={Communications in Theoretical Physics}, year={2020}, volume={72} }

We explore the existence of monogamy relations in terms of Rényi-α entanglement. By using the power of the Rényi-α entanglement, we establish a class of tight monogamy relations of multiqubit entanglement with larger lower bounds than the existing monogamy relations for α ≥ 2, the power η > 1, and 2 > α ≥ 7 − 1 2 , the power η > 2, respectively.
