论文摘要

与当地环境相比,一类有趣的物理系统(包括与生活相关的物理系统)表明,在海湾持有热化的能力并使高自由能的状态永存。在这项工作中,我们研究没有外部来源或水槽的量子系统,以用于能量,热量,工作或熵,从而使高自由能子系统形成和持久。我们初始化混合,不相关状态的Qubits系统,并遵守保护法。我们发现四个量子位构成了这些限制动力学和初始条件的最小系统,可以增加子系统的可提取工作。在每个步骤中随机选择子系统中相互作用的八个共同进化量子的景观上,我们证明了限制的连通性和初始温度的不均匀分布都导致景观导致景观,并且较长的间隔是增加单个量子比的可提取工作的较长间隔。我们证明了相关性在景观中发展在可提取工作的积极变化中的作用。

An interesting class of physical systems, including those associated with life, demonstrates the ability to hold thermalization at bay and perpetuate states of high free-energy compared to a local environment. In this work, we study quantum systems with no external sources or sinks for energy, heat, work, or entropy, that allow for high free-energy subsystems to form and persist. We initialize systems of qubits in mixed, uncorrelated states and evolve them subject to a conservation law. We find that four qubits make up the minimal system for which these restricted dynamics and initial conditions allow an increase in extractable work for a subsystem. On landscapes of eight co-evolving qubits, interacting in randomly selected subsystems at each step, we demonstrate that restricted connectivity and an inhomogeneous distribution of initial temperatures both lead to landscapes with longer intervals of increasing extractable work for individual qubits. We demonstrate the role of correlations that develop on the landscape in enabling a positive change in extractable work.
