论文摘要
我们解决了第二定律受到质疑的新环境：因果订单的量子叠加中的热量，由所谓的量子开关制定。该叠加已被证明与通道的通信能力增加有关，从而显然违反了数据处理不平等，并且有可能将热与寒冷分开。我们分析了此信息能力增加过程的热力学。我们展示了信息能力增加与热力学的兼容。我们表明，如果将它们以不确定的顺序放置，并且只有只有显着界限的增加才有可能，那么连续热量的连续热量可能确实会增加信息能力。增加是以消耗热力学资源为代价的，即与开关相关的连贯性的自由能。
We address a new setting where the second law is under question: thermalizations in a quantum superposition of causal orders, enacted by the so-called quantum switch. This superposition has been shown to be associated with an increase in the communication capacity of the channels, yielding an apparent violation of the data-processing inequality and a possibility to separate hot from cold. We analyze the thermodynamics of this information capacity increasing process. We show how the information capacity increase is compatible with thermodynamics. We show that there may indeed be an information capacity increase for consecutive thermalizations obeying the first and second laws of thermodynamics if these are placed in an indefinite order and moreover that only a significantly bounded increase is possible. The increase comes at the cost of consuming a thermodynamic resource, the free energy of coherence associated with the switch.
