我们引入了一个严格的框架来量化一致性，并确定了直观和易于计算的一致性度量。我们通过采用连贯作为物理资源的观点来实现这一点。通过确定一致性度量的定义条件，我们确定了满足这些条件的泛函类别，以及乍看起来不符合一致性度量的其他自然量。最后，我们概述了一些有待回答的问题，以完善作为资源的一致性理论。
We introduce a rigorous framework for the quantification of coherence and identify intuitive and easily computable measures of coherence. We achieve this by adopting the viewpoint of coherence as a physical resource. By determining defining conditions for measures of coherence we identify classes of functionals that satisfy these conditions and other, at first glance natural quantities, that do not qualify as coherence measures. We conclude with an outline of the questions that remain to be answered to complete the theory of coherence as a resource.
