摘要翻译:
导出了一个新的热力学不等式,该不等式在离散量子反馈控制的辅助下,导出了多个热浴中的最大功。最大功由热力学系统与反馈控制器之间的自由能差和广义互信息量决定。这个最大功可以超过传统热力学中的最大功,在两个热浴的热循环中,热效率可以大于卡诺循环的热效率。由于反馈控制器的信息处理需要做功,从而保证了我们的结果与热力学第二定律的一致性。

英文摘要:
A new thermodynamic inequality is derived which leads to the maximum work that can be extracted from multi-heat baths with the assistance of discrete quantum feedback control. The maximum work is determined by the free-energy difference and a generalized mutual information content between the thermodynamic system and the feedback controller. This maximum work can exceed that in conventional thermodynamics and, in the case of a heat cycle with two heat baths, the heat efficiency can be greater than that of the Carnot cycle. The consistency of our results with the second law of thermodynamics is ensured by the fact that work is needed for information processing of the feedback controller.
