Work gain correlates with changes in mutual information.

Feedback control based on measurement exploits quantum correlations.

Abstract

We show that entanglement can be utilized to extract thermodynamic work beyond classical correlation via feedback control based on measurement on part of a composite system. The net work gain due to entanglement is determined by the change in the mutual information content between the subsystems that is accessible by the memory.
