What can logic learn from quantum mechanics

We give a logical analysis of quantum measurements as forms of information update. We enumerate some of the “lessons ” that Logic can learn from Quantum Mechanics: (1) the importance of logical dynamics; (2) the fact that quantum physics does not require any modification of the classical laws of “static ” propositional logic, but only a non-classical dynamics of information flow; (3) the fact that all information-gathering actions have ontic side-effects; (4) the fact that this ontic impact might in its turn affect the flow of information, leading to non-classical epistemic effects and to states of “objectively imperfect information”.
