Monogamy and Polygamy Relations of Quantum Correlations for Multipartite Systems

Tighter monogamy relations of entanglement measures based on fidelity

“…, in the following examples we will see that ∆m ⩾ 0, so our results are tighter than those in [22,27,28] for 0 ⩽ α ⩽ η 2 and η ⩾ 1. Example 1.…”

“…x 2 0.13166 x respectively. Figure 2 depicts the value of y for 0 ⩽ x ⩽ 1 2 , which shows that theorem 1 supplies a better estimation of the Bures measure of entanglement than those of [27,28].…”

“…) [28], and [27] respectively. Let ∆m = m − m i , i = 1, 2, 3, in the following examples we will see that ∆m ≥ 0, so our results are tighter than those in [22,27,28] for…”

“…Remark 2. We use the Bures measure of entanglement as an example to compare our result with those in [22,27,28]. In tripartite quantum systems, when…”
