[Hawkwind]

Zitat von RoKo

Hallo Hawkwind,


Eine Beobachtung muß erklärt werden. Die o.a. Erklärungen gehen vom "Kollaps der Wellenfunktion" im Falle der Messung aus. Er ist notwendiger Bestandteilder Erklärung. - oder siehst du das anders?

Ja natürlich sehe ich das anders: der Quanten-Zeno-Effekt ist eine Vorhersage des interpretationsunabhängigen Kerns der Quantenmechanik.

siehe z.b:

Arguments on controversial points concerning quantum measurement theory and the quantum Zeno effect are presented. In particular it is argued that (1) the quantum Zeno effect is a genuine result of quantum theory and current quantum measurement theory, independent of the projection postulate; (2) the effect is of very general nature and rests on analogous arguments to those involved in Bell's theories; (3) the term “quantum Zeno effect” may usefully be restricted to experiments where a measuring device exerts a nonlocal negative-result effect on a microscopic system, mere inhibition of a transition by a directly interacting device not qualifying; (4) since no decay is truly exponential, theoretically all decay phenomena should exhibit the quantum Zeno effect under observation, continuous or discrete. ...

im besonderen existiert dieser Effekt natürlich auch in Everetts vielen Welten:

The quantum Zeno paradox is examined within the many-worlds and relative states interpretations of quantum mechanics. In the many-worlds interpretation the effect is predicted to persist. The possibility of recombining worlds is not expected to be relevant. In the simplest form of relative states interpretation the effect may be avoided but this form of interpretation experiences difficulties in coping with conventional problems of quantum theory. The more complex version of the relative states interpretation, which takes account of the correlations of system with apparatus, predicts the occurrence of the paradox.
