The design and implementation of quantum technologies necessitates the understanding of thermodynamic processes in the quantum domain. In stark contrast to macroscopic thermodynamics, at the quantum scale processes generically operate far from equilibrium and are governed by fluctuations. Thus, experimental insight and empirical findings are indispensable in developing a comprehensive framework. To this end, we theoretically propose an experimentally realistic quantum engine that uses transmon qubits as working substance. We solve the dynamics analytically and calculate its efficiency.
量子技术的设计与实现需要理解量子领域的热力学过程。与宏观热力学形成鲜明对比的是，在量子尺度下，过程通常远离平衡态运行且受涨落支配。因此，实验洞察和实证研究结果对于构建一个全面的框架不可或缺。为此，我们从理论上提出了一种实验上可行的量子引擎，它使用跨导量子比特作为工作物质。我们解析求解了动力学过程并计算了其效率。
