I never said it had to control Shrodinger's mind. It just has to convince him of it. For instance, him changing location but you make him believe it failed and he's still in the same place.
Not to mention Schroedinger is able to literally enter your mind, I would wager his Quantum Reality Warping overrides any Genjutsu.
