Abstract: Information-theoretic aspects of quantum inseparability of mixed states are investigated in terms of the \ensuremath{\alpha} entropy inequalities and teleportation fidelity. Inseparability of mixed states is defined and a complete characterization of the inseparable 2\ifmmode\times\else\texttimes\fi{}2 systems with maximally disordered subsystems is presented within the Hilbert-Schmidt space formalism. A connection between teleportation and negative conditional \ensuremath{\alpha} entropy is also emphasized. \textcopyright{} 1996 The American Physical Society.
