Clauser-Horne-Shimony-Holt violation and the entropy-concurrence plane

We characterize violation of Clauser-Horne-Shimony-Holt (CHSH) inequalities for mixed two-qubit states by their mixedness and entanglement. The class of states that have maximum degree of CHSH violation for a given linear entropy is also constructed.

Nonlocality activation in entanglement-swapping chains

We consider multiple entanglement swappings performed on a chain of bipartite states. Each state does not violate Clauser-Horne-Shimony-Holt (CHSH) inequality. We show that before some critical number of entanglement swappings is achieved the output state does not violate this inequality either. However, if this number is achieved, then for some results of Bell measurements obtained in the protocol of entanglement swapping the output state violates CHSH inequality. Moreover, we show that for different states we have different critical numbers for which CHSH inequality is activated.
