Physical Review A

Incomplete ‘‘collapse’’ and partial quantum Zeno effect

Abstract

If the interaction generating a quantum measurement is too weak to completely ''collapse'' the wave function, a partial quantum Zeno effect may result. An experimental test is proposed.Received 4 April 1990DOI:https://doi.org/10.1103/PhysRevA.42.5720©1990 American Physical Society

Quantum Zeno Effect in the Measurement Problem

Mikio Namiki, Saverio Pasaczio

Critically analyzing the so-called quantum Zeno effect in the measurement problem, we show that observation of this effect does not necessarily mean experimental evidence for the naive notion of wave-function collapse by measurement (the simple projection rule). We also examine what kind of limitation the uncertainty relation and others impose on the observation of the quantum Zeno effect.

Quantum Zeno Effect by Incomplete Measurements

Manchao Zhang, Chun-Wang Wu, Yi Xie +2 more

We investigate the quantum Zeno effect caused by incomplete measurements. We show that a more efficient quantum Zeno effect than the complete measurements case can occur if parameters are properly set.

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

Wayne M. Itano, Daniel J. Heinzen, J. J. Bollinger +1 more

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.
