摘要:
我们提出了一种热力学功提取任务,用于描述量子系统的储能增强。该任务诱导出类优超条件,为一般量子资源理论中的态转换提供了充要表征。将其应用于特定资源时,这些条件在保幺信道下简化为优超条件,还给出了纠缠理论中Nielsen定理的热力学版本。我们展示该结果如何确立首个基于热力学的通用资源认证类别,以及如何利用它基于功提取量化一般量子资源。
英文摘要:
We introduce a thermodynamic work extraction task that describes the energy storage enhancement of quantum systems. This task induces majorisation-like conditions that provide a necessary and sufficient characterisation of state conversions in general quantum resource theories. When applied to specific resources, these conditions reduce to the majorisation conditions under unital channels and provide a thermodynamic version of Nielsen's theorem in entanglement theory. We show how this result establishes the first universal resource certification class based on thermodynamics, and how it can be employed to quantify general quantum resources based on work extraction.
