Deformed entropic and information inequalities for X - states of   two-qubit and single qudit states
  The q-deformed entropies of quantum and classical systems are discussed. Standard and q-deformed entropic inequalities for X - states of the two-qubit and a state of single qudit with $j=3/2$ are presented.
