TL;DR
This paper introduces a systematic method to tighten monogamy relations in multipartite quantum systems by developing parametrized bounds, leading to more accurate lower bounds than previous relations.
Contribution
The paper presents a new family of parametrized bounds that systematically tighten monogamy relations in quantum systems, improving upon existing bounds.
Findings
New parametrized bounds are tighter than previous monogamy relations.
Examples demonstrate the superiority of the proposed bounds.
The method provides a systematic approach to improve monogamy relations.
Abstract
We seek a systematic tightening method to represent the monogamy relation for some measure in multipartite quantum systems. By introducing a family of parametrized bounds, we obtain tighter lowering bounds for the monogamy relation compared with the most recently discovered relations. We provide detailed examples to illustrate why our bounds are better.
