论文摘要
在这项工作中，我们得出了纠缠与连贯性之间的分析关系，以及不一致与连贯性之间的分析关系，对于钟形式状态和x状态，在几个噪声通道的作用下演变：位换位，相阻尼和去极化。我们证明，对于这些家庭来说，连贯性是基本的相关性，也就是说：一致性对于存在纠缠和不和谐是必不可少的。
In this work we derive analytical relations between Entanglement and Coherence as well as between Discord and Coherence, for Bell-diagonal states and for X states, evolving under the action of several noise channels: Bit Flip, Phase Damping and Depolarizing. We demonstrate that for these families, Coherence is the fundamental correlation, that is: Coherence is necessary for the presence of Entanglement and Discord.
