The quantum zeno effect

WebbThe dynamical quantum Zeno effect is studied in the context of von Neumann algebras. We identify a localized subalgebra on which the Zeno dynamics acts by automorphisms. The Zeno dynamics coincides with the modular dynamics of that subalgebra, if an additional assumption is satisfied. This relates the modular operator of that subalgebra … Webb12 juli 2024 · The “quantum Zeno effect” is a special physical situation where a “system” is “observed” very “intensively”.

WebbBut now we can see a quantum analog: we can also have motion in the branchlike direction, in which, in effect, we progressively sample more branchlike edges, reaching more quantum states. Velocity in space is thus the analog of the rate at which additional states are sampled (and thus entangled).
