摘要

In this review,we introduce well-known Bell inequalities,the relations between the Bell inequality and quantum separability,and the entanglement distillation of quantum states.It is shown that any pure entangled quantum state violates one of Bell-like inequalities.Moreover,quantum states that violate any one of these Bell-like inequalities are shown to be distillable.New Bell inequalities that detect more entangled mixed states are also introduced.
