论文摘要
热力学的第二定律禁止从寒冷到热体的自发热量。但是，从理论上和实验上表明，如果身体最初相关，能量可以从寒冷流向热体。我们研究了最初纠缠的无量子量子系统之间的\ emph {异常能量交换}。然后，我们扩展了该模型以包括耗散，证明了\ emph {异常热}从冷到热体。基于这些模型，我们构建了一个完全由量子相关驱动的热泵，并通过数值模拟研究了其性能。使用最近提出的基于相互信息的效率定义，发现泵的性能与热力学的第二定律一致。
The second law of thermodynamics prohibits spontaneous heat from a cold to a hot body. However, it has been theoretically and experimentally shown that energy can flow from a cold to a hot body if the bodies are initially correlated. We investigated the \emph{anomalous energy exchange} between dissipation-less quantum systems that are initially entangled. Then, we extended this model to include dissipation demonstrating \emph{anomalous heat} from a cold to a hot body. Based on these models, we constructed a heat pump driven entirely by quantum correlation as fuel and investigated its performance with numerical simulations. Using the recently proposed definition of efficiency based on mutual information, the performance of the pump is found to be consistent with the second law of thermodynamics.
