Monogamy of entanglement measures based on fidelity in multiqubit systems

Tighter monogamy relations of entanglement measures based on fidelity

“…≈ 0.02880, and The lower bound in [22] is shown by the yellow surface and the blue surface is our result in Theorem 1.…”

“…) [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 M η B (ρ…”

Tighter monogamy relations in multiparty quantum systems

“…, and µ ≥ 1, we get the inequality (29). Combining inequalities ( 28) and ( 29), we can get the inequality (27).…”

“…Tsallis entropy [21][22][23], Rényi entropy [24,25], unified entropy [26,27], geometric measure [28,29] and so on. The research for tight monogamy relations has also attracted widespread attention in the past decade.…”
