论文摘要
连贯的叠加和纠缠是非古典性的两个基本方面。在这里，我们通过表明操作的动力连贯性在操作水平上提供了定量连接，该操作的动力连贯性可以借助其他不连贯的操作，可以从中产生的动力纠缠。如果使用基于相对熵的单调选择的特定选择用于定量这些动力学资源，则可以实现此界限。此外，我们表明对纠缠势的类似物存在于操作水平上，并作为动力相干性的有效量化器。
Coherent superposition and entanglement are two fundamental aspects of non-classicality. Here we provide a quantitative connection between the two on the level of operations by showing that the dynamical coherence of an operation upper bounds the dynamical entanglement that can be generated from it with the help of additional incoherent operations. In case a particular choice of monotones based on the relative entropy is used for the quantification of these dynamical resources, this bound can be achieved. In addition, we show that an analog to the entanglement potential exists on the level of operations and serves as a valid quantifier for dynamical coherence.
