The study of quantum thermodynamics aims to elucidate the role played by quantum principles in the emergent features of quantum thermodynamic processes. Specifically, it is of fundamental importance to understand how quantum correlation among different parties enables thermodynamic features distinguishable from those arising in classical thermodynamics. In this work, we investigate the relation between extractable work and quantum correlations for two-mode Gaussian states. We examine the change in local energy occurring at one party due to a Gaussian measurement performed on the other in relation to the quantum correlations of two-mode states classified as separable, entangled, and steerable states. Our analysis reveals a clear quantitative difference in the extractable work, depending on the class of states to which the two-mode state belongs.
量子热力学的研究旨在阐明量子原理在量子热力学过程的涌现特征中所起的作用。具体而言,理解不同部分之间的量子关联如何使热力学特征有别于经典热力学中出现的特征至关重要。在这项工作中,我们研究了双模高斯态的可提取功与量子关联之间的关系。我们考察了由于对另一方进行高斯测量而在一方发生的局部能量变化,这与被分类为可分态、纠缠态和可操纵态的双模态的量子关联有关。我们的分析揭示了可提取功存在明显的定量差异,这取决于双模态所属的态类别。
