Tighter bounds for generalized monogamy and polygamy relations

Quantum Physics 2024-11-07 v1

Abstract

We study generalized monogamy and polygamy relations for concurrence of assistance and negativity of assistance using parametrized bounds in general multi-partite quantum systems. The new method overcomes the shortcomings of previous studies where a method is only good at a particular region. We provide detailed examples to show why the new approach is effective in all regions.
