The information on a quantum process acquired through measurements plays a crucial role in the determination of its nonequilibrium thermodynamic properties. We report on the experimental inference of the stochastic entropy production rate for a continuously monitored mesoscopic quantum system. We consider an optomechanical system subjected to continuous displacement Gaussian measurements and characterize the entropy production rate of the individual trajectories followed by the system in its… Expand

Infima statistics of entropy production in an underdamped Brownian motor.
This paper has constructed a horizontal Brownian motor immersed in a granular gas, whose dynamics is governed by the underdamped stochastic process, and experimentally demonstrates that, despite the nonideal elements in the experiments and that the complex underlying dynamics, the average value of the minima of the negative entropy production is still bounded by -k_{B}.

Information thermodynamics on causal networks.
The result implies that the entropy production in a single system in the presence of multiple other systems is bounded by the information flow between these systems, which is similar to the second law of thermodynamics. Expand

Stochastic thermodynamics with arbitrary interventions.
For a driven system in contact with a single heat bath the four key thermodynamic quantities are defined along a single "trajectory" for a causal model and a classical version of Stinespring's dilation theorem is proved, which might be of independent interest. Expand
