Abstract
Bell inequality plays a crucial role in the debate between quantum mechanical completeness and local realism. It vigorously promoted researches on these aspects, macroscopic quantum superposition states, especially entangled states, and it has brought the debate from theory to experiment, which generated a new discipline, quantum information theory. Thus, this work briefly summarizes some major situations in the verification process of Bell inequality. At the same time, this work analyses existent some problems in the verification process of Bell inequality, and states own perception for the debate.This work can help people better understand the foundation knowledge of quantum information theory, thus quantum information theory can be applied to more actual situations.
