maxwell's demon, ignoring thermodynamics by being omniscient and being omnipotent. simple terms is that you can reverse entropy if you only let things that are hotter than the hot side go to the hot side.
laplace's demon, telling the future from a snapshot of now. if you have perfect information, you can calculate exactly how the world will turn.
schrodinger's cat, when something is in unobserved state of being that can be one of multiple states based on random probability, (there are multiple interpretations of this) it is all states at once until observed.
