论文摘要
我们报告了对非平衡熵产生的贡献的实验量化，这源于暴露于相干驾驶和耗散的量子量的初始状态下的量子相干含量。我们的实验演示基于对钻石中氮呈缺陷的自旋状态的精致实验控制，从理论上讲，基于旨在跟踪量子相干性效果的广义波动定理的表述。我们的结果提供了重要的证据，证明可能对非平衡量子过程的热力学的真正量子机械贡献进行了真正的可能性。
We report the experimental quantification of the contribution to non-equilibrium entropy production that stems from the quantum coherence content in the initial state of a qubit exposed to both coherent driving and dissipation. Our experimental demonstration builds on the exquisite experimental control of the spin state of a nitrogen-vacancy defect in diamond and is underpinned, theoretically, by the formulation of a generalized fluctuation theorem designed to track the effects of quantum coherence. Our results provide significant evidence of the possibility to pinpoint the genuinely quantum mechanical contributions to the thermodynamics of non-equilibrium quantum processes.
