General tradeoff relations of quantum nonlocality in the Clauser-Horne-Shimony-Holt scenario

TL;DR

This paper investigates fundamental tradeoff relations in quantum nonlocality within bipartite systems, highlighting their generality beyond specific states, and explores connections with uncertainty principles and extensions to multipartite cases.

Contribution

It introduces general tradeoff relations for quantum nonlocality that are independent of specific states or measurement directions, and discusses their extensions and relation to uncertainty principles.

Findings

Tsirelson's bound can be derived from these tradeoff relations.

Tradeoff relations are applicable to bipartite systems regardless of states or measurement choices.

Extensions to multipartite scenarios are feasible and promising.

Abstract

General tradeoff relations present in nonlocal correlations of bipartite systems are studied, regardless of any specific quantum states and measuring directions. Extensions to multipartite scenarios are possible and very promising. Tsirelson's bound can be derived out in particular. The close connection with uncertainty relations is also presented and discussed.
