| 摘 要： | 非广延熵纠缠是一种很好的纠缠度量方式，其本身在参数q∈［2，3］范围服从严格单配性关系.我们提出基于非广延熵纠缠平方服从的严格单配性关系，将参数范围扩展至q∈（5-√13]）/2，（5+√13）/2].该单配性关系更加严格，比非广延熵纠缠的严格单配性不等式成立范围更广.

| Abstract: | Tsallis-q entanglement is a well-known entanglement measures which obeys a tighter monogamy inequality with q∈2,3]. We extend the range of q for analytic formula of Tsallis-q entanglement to q∈(5-√13)/2,(5+√13)/2], and prove that it is a tighter monogamy inequality of quantum entanglement in terms of squared Tsallis-q entanglement. It is tighter than existing ones,and the range of q become broader than tighter monogamy inequality using Tsallis-q entanglement. |
