The most succinct manifestation of the second law of thermodynamics is the limitation the Landauer principle imposes on the amount of heat a Maxwell demon (MD) can convert into free energy per single bit of information obtained in a measurement. We suggest and experimentally realize a reversible electronic MD based on a single-electron box operated as a Szilard engine, providing the first demonstration of this limitation: extraction of kT ln 2 of heat from the reservoir at temperature T per one bit of created information. The information is encoded in the position of an extra electron in the box.
