Reply to ‘‘Comment on ‘Quantum Zeno effect’’’

Abstract
Various interpretations of quantum mechanics are valid insofar as they predict the same experimental results. Some invoke ‘‘wave-function collapse’’ and some do not. An interpretation based on the collapse postulate provides a simple explanation for a recent experimental demonstration of the quantum Zeno effect [Itano et al., Phys. Rev. A 41, 2295 (1990)], but other interpretations are also valid.
