摘要
Information-theoretic aspects of quantum inseparability of mixed states are investigated in terms of the alpha entropy inequalities and teleportation fidelity. Inseparability of mixed stares is defined and a complete characterization of the inseparable 2x2 systems with maximally disordered subsystems is presented within the Hilbert-Schmidt space formalism. A connection between teleportation and negative conditional alpha entropy is also emphasized.
