Tighter parameterized monogamy relations

  • Published:
Quantum Information Processing Aims and scope Submit manuscript

Abstract

We seek a systematic tightening method to represent the monogamy relation for some measure in multipartite quantum systems. By introducing a family of parameterized 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.
