本文报道了在封闭量子系统中非平衡功几率分布的实验重建，以及相应的量子涨落关系的研究。该实验使用液态核磁共振平台，可完全控制系统的制备和动力学。我们的努力使得从有限时间热力学的角度来描述量子自旋的非平衡动力学。
We report the experimental reconstruction of the nonequilibrium work probability distribution in a closed quantum system, and the study of the corresponding quantum fluctuation relations. The experiment uses a liquid-state nuclear magnetic resonance platform that offers full control on the preparation and dynamics of the system. Our endeavors enable the characterization of the out-of-equilibrium dynamics of a quantum spin from a finite-time thermodynamics viewpoint.
