论文摘要
揭示了特定于量子力学现象的热力学的影响是确定热发动机中量子操作和量子优势的基本成本的关键步骤。我们提出了一个两库设置，以检测由与其热环境相干驱动的原子交换的热流中的量子分量。调整驱动参数的打开和关闭量子和经典贡献对热流的贡献，从而使其独立表征。我们证明了在电路QED设置中测量的可行性。我们的结果铺平了通往该量子热力学特征无处不在的量子技术的首次实验验证的道路。
Unveiling the impact in thermodynamics of the phenomena specific to quantum mechanics is a crucial step to identify fundamental costs for quantum operations and quantum advantages in heat engines. We propose a two-reservoir setup to detect the quantum component in the heat flow exchanged by a coherently driven atom with its thermal environment. Tuning the driving parameters switches on and off the quantum and classical contributions to the heat flows, enabling their independent characterization. We demonstrate the feasibility of the measurement in a circuit-QED setup. Our results pave the road towards the first experimental verification of this quantum thermodynamic signature ubiquitous in quantum technologies.
