We present a class of tight monogamy relations in terms of Renyi-$\alpha$ entanglement, which are tighter than the monogamy relations of multiqubit entanglement just based on the power of the Renyi-$\alpha$ entanglement for $\alpha\geq 2$ and the power $\eta>1$. For $2>\alpha\geq\frac{\sqrt{7}-1}{2}$ 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.

在 Rényi-α 纠缠方面更紧密的多量子比特纠缠的一夫一妻制关系

我们在 Renyi-$\alpha$ 纠缠方面提出了一类紧密的一夫一妻制关系,它比仅基于 Renyi-$\alpha$ 纠缠对 $\alpha\geq 2 的幂的多量子比特纠缠的一夫一妻制关系更紧密$ 和幂 $\eta>1$。对于 $2>\alpha\geq\frac{\sqrt{7}-1}{2}$ 和幂 $\eta>2$,我们建立了一类多量子位纠缠的紧密一夫一妻制关系,其下界比现有的大多量子比特纠缠的一夫一妻制关系。
