Yes it is. When I took Feynman’s class on computation, he presented an argument on Landauer’s limit. It involved a multi-well quantum potential where the barrier between the wells was slowly lowered and the well depths adjusted. During the argument, one of the students asked if he had not just introduced a Maxwell’s demon. Feynman got very defensive.
This is a very good tip and one of Richard Feynman’s better known tricks in physics.
