Nonlocality for many configurations of measurements

Abstract

Quantum Nonlocality conflicts with any local-realistic theories. It is at the heart of quantum mechanics and also plays essential roles in quantum information processing. In 1964, Bell show that there is an upper limit to the correlation between distant events which must be obeyed by any local-realistic theories but violated by quantum mechanics. In this time, we investigate the nonlocality of complex system, which is multipartite, many configurations and high dimension. For the purpose we propose a generic Bell inequality, which deduces GHZ nonlocality for many configurations. We show that it is violated by quantum mechanics. We also discuss the structure of the presently derived inequality.
