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

Noise-induced finite-time disentanglement in two-atomic system
Lech Jakobczyk, Anna Jamroz
We discuss the influence of a noisy environment on entangled states of two atoms and show that all such states disentangle in finite time.

Bell inequalities versus entanglement and mixedness for a class of two - qubit states
L. Derkacz, L. Jakobczyk
For a class of mixed two -qubit states we show that it is not possible to discriminate between states violating or non - violating Bell - CHSH inequalities, knowing only their enta…
