标题： Experimental investigation of coherence contributions to a nonequilibrium thermodynamic process in a driven quantum system

摘要： 当一个处于热平衡的系统被一个单位控制参数外部驱动时，会导致不可逆熵的产生。 产生的熵可以看作是相干性生成和目标平衡态与实际达到的最终态之间的种群不匹配的组合。 我们在核磁共振量子处理器中实验研究了这一非平衡过程，并研究了相干性对不可逆熵生成的贡献。 我们验证了一个广义的克拉佩龙不等式，该不等式确认不可逆熵的产生有一个下限。 显示英文摘要

摘要： The work done when a system at thermal equilibrium is externally driven by a unitary control parameter leads to irreversible entropy production. The entropy produced can be thought of as a combination of coherence generation and a population mismatch between the target equilibrium state and the actually achieved final state. We experimentally explored this out-of-equilibrium process in an NMR quantum processor and studied the contribution of coherence to irreversible entropy generation. We verified a generalized Clausius inequality, which affirms that irreversible entropy production is lower-bounded.
