论文摘要
我们通过表明后者在一般上下文中确定了线性响应制度中经典和量子动力学之间的基本差异。这使我们能够提供一个量子引擎的示例，其有利的功率输出缩放\ emph {不可避免地需要以情境性的形式进行非经典效应。此外，我们描述了本地计量学的上下文优势。鉴于线性响应理论的普遍性，我们预计这些工具将允许人们证明各种量子现象的非古老性。
We identify a fundamental difference between classical and quantum dynamics in the linear response regime by showing that the latter is in general contextual. This allows us to provide an example of a quantum engine whose favorable power output scaling \emph{unavoidably} requires nonclassical effects in the form of contextuality. Furthermore, we describe contextual advantages for local metrology. Given the ubiquity of linear response theory, we anticipate that these tools will allow one to certify the nonclassicality of a wide array of quantum phenomena.
