Tighter monogamy relations of multiqubit entanglement in terms of Rényi-α entanglement |
| |
摘 要: | 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 η1, and 2α≥(7~(1/2)-1)/2, the power η2, respectively.

Abstract: | 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 $2\gt \alpha \geqslant \tfrac{\sqrt{7}-1}{2}$, the power η>2, respectively. |
