Violation of Clauser-Horne-Shimony-Holt inequality for states resulting from entanglement swapping
arXiv:1007.4775 · doi:10.1016/j.physleta.2010.09.069
Abstract
We consider violation of CHSH inequality for states before and after entanglement swapping. We present a pair of initial states which do not violate CHSH inequality however the final state violates CHSH inequality for some results of Bell measurements performed in order to swap entanglement.
