Maxwell’s demon with a Szilard box, as proposed by Bennett. A measurement detects on which side of the inserted separator the particle is, and extracts work with a piston in either case. The cylinder is left in its original state, apparently creating a perpetuum mobile with net work gain. However, the measurement outcome (represented by ‘L’ or ‘R’) had to be stored in a memory register, which was initially in some pure state (represented by ‘—’) and the work cost of resetting it to a pure state again compensates the work gain.
