We investigate entropic aspects of the quantum entanglement dynamics of two-qubits systems interacting with an environment. In particular we consider the detection, based on the violation of classical entropic inequalities involving q-entropies, of the phenomenon of entanglement disappearance and subsequent entanglement revival during the alluded two-qubits’ evolution.q-entropies, of the phenomenon of entanglement disappearance and subsequent entanglement revival during the alluded two-qubits’ evolution.
