Information plays an important role in evolution of monitored classical and quantum mesoscopic systems. The most basic device illustrating the role of information in thermodynamics is Maxwell's Demon (MD) which employs the measurements and feedback to convert energy of thermal fluctuations into free energy. An ideal, fully reversible, MD would use only well-defined initial state of a memory register to achieve this task. Experimental demonstration of such MD is an open problem, with one of the main obstacles being the development of the thermodynamically reversible detectors. In the talk, I will discuss possible ways of implementing electronic MD based on transport in mesoscopic structures and related statistics of heat fluctuations in these systems. Connections to thermodynamics of quantum measurements will also be discussed.
