摘要：

The necessary and sufficient condition for violating the Clauser-Horne-Shimony-Holt (CHSH) inequality by an arbitrary mixed spin-1/2 state is presented. Some examples of mixtures which demonstrate the utility of the condition are considered. In particular, it is shown that the local hidden variable (LHV) model for mixed states introduced by Werner [Phys. Rev. A 40 (1989) 4277] is forbidden in some region.
