中文摘要：

证明了量子操控椭球等同于量子通道椭球．建立了量子失谐与量子通道之间的密切联系．指出量子失谐的核心部分，即基于测量的量子条件熵，等价于量子通道的纠缠熵．

英文摘要：

Quantum steering ellipsoid and quantum channel ellipsoid was proved to be equivalent with each other. The relationship between quantum discord and quantum channel was manifested where the essential part of quantum discord, that is, the quantum conditional entropy based on quantum measurement, was proved equal to the entanglement entropy of quantum channel.
