Query: Experimental realization of a Szilard engine with a single electron   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.
