反馈可用于将信息转化为有用的功，使其成为提高热力发动机性能的有效工具。使用反馈可逆性作为指导原则，我们设计了一种为热力发动机设计最佳反馈协议的方法，该方法提取在反馈过程中获得的所有信息作为工作。我们的方法基于这样的观察：在反馈可逆过程中，随后协议的测量和时间反转都使系统处于相同的概率状态。我们用多粒子西拉德引擎的两个例子来说明我们的方法的实用性。
Feedback can be utilized to convert information into useful work, making it an effective tool for increasing the performance of thermodynamic engines. Using feedback reversibility as a guiding principle, we devise a method for designing optimal feedback protocols for thermodynamic engines that extracts all the information gained during feedback as work. Our method is based on the observation that in a feedback-reversible process the measurement and the time-reversal of the ensuing protocol both prepare the system in the same probabilisticstate. We illustrate the utility of our method with two examples of the multi-particle Szilard engine.
