    "abstract": "The quantum Zeno evolution of a quantum system takes place in a proper\nsubspace of the total Hilbert space. The physical and mathematical features of\nthe \"Zeno subspaces\" depend on the measuring apparatus: when this is included\nin the quantum description, the Zeno effect becomes a mere consequence of the\ndynamics and, remarkably, can be cast in terms of an adiabatic theorem, with a\ndynamical superselection rule. We look at several examples and focus on quantum\ncomputation and decoherence-free subspaces.",
