根据α熵不等式和隐形传态保真度研究了混合态量子不可分离性的信息论方面。定义了混合凝视的不可分离性，并在希尔伯特-施密特空间形式主义中给出了具有最大无序子系统的不可分离 2x2 系统的完整表征。还强调了隐形传态和负条件阿尔法熵之间的联系。
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.
