Abstract
We validate experimentally a fluctuation relation known
as generalized Jarzynski equality governing the work
distribution in a feedback-controlled system. The
feedback control is performed on a single electron box
analogously to the original Szilard engine. In the
generalized Jarzynski equality, mutual information is
treated on an equal footing with the thermodynamic work.
Our measurements provide the first evidence of the role
of mutual information in the fluctuation theorem and
thermodynamics of irreversible processes.
