    • Note, that probability of occupying a certain region of the phase space in classical (chaotic, or mixing) Hamiltonian systems also decays quadratically with time due to the time reversal symmetry. Zeno effect is quantum only in the following sense: in quantum mechanics the detection of whether the system is in the initial state, collapses the system to that state. If we take a classical decaying system, perform measurements, and then perform some operations on the system that at least with some probability put it back into the initial state, we would, of course, have a classical version of the Zeno effect. It is worth noticing that classical error correction schemes are based on this idea, see discussion in the context of quantum correction schemes in computing and information processing 4
