Experimental reconstruction of work distribution and study of fluctuation relations in a closed quantum system

Phys Rev Lett. 2014 Oct 3;113(14):140601. doi: 10.1103/PhysRevLett.113.140601. Epub 2014 Oct 3.


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.
