Bell inequalities and linear entropy. Comment on the paper of E. Santos "Entropy inequalities and Bell inequalities fro two-qubit systems"

Lech Jakóbczyk

It is shown that even if the linear entropy of mixed two-qubit state is not smaller then 0.457, Bell - CHSH inequalities can be violated. This contradicts the result obtained in the paper of E. Santos [1].
