Comment on ‘Two-state vector formalism and quantum interference’

Lev Vaidman A

Published Sep 19, 2017• 22 citations
Publisher

Abstract

Abstract Hashmi et al (2016 J. Phys. A: Math. Theor . 49 345302) claimed that the approach to the past of a quantum particle introduced by Vaidman (2013 Phys. Rev . A 87 052104) has difficulties in certain examples and that it can even be refuted. Here I reply to their criticism showing that the approach provides a good explanation for all the examples they considered. It is fully consistent with standard quantum mechanics and provides a useful tool for analyzing interference experiments.

Abstract In the preceding comment it is claimed that we are mistaken in the analysis of the theory of the ‘past of a quantum particle’ proposed by the author of the comment. We show that the claim is unfounded. Moreover we show that the arguments presented in the comment are not consistent with the already proposed theory.

We stand by our findings in Phys. Rev. A 96, 022126 (2017). In addition to refuting the invalid objections raised by Peleg and Vaidman, we report a retrocausation problem inherent in Vaidman's definition of the past of a quantum particle.

Comment on “Particle path through a nested Mach-Zehnder interferometer”

Lev Vaidman A

Griffiths [Phys. Rev. A 94, 032115 (2016)] analyzed, in the framework of a consistent histories interpretation, the controversy regarding the approach to the past of a quantum particle introduced by Vaidman [Phys. Rev. A 87, 052104 (2013)]. I argue that Griffith's criticism of my approach using an analysis of experiments with weak probes is unfounded.

In our recent paper [Phys. Rev. A 91, 012103 (2015)] we have provided an alternative description of a highly debated experiment by Danan et al. [Phys. Rev. Lett. 111, 240402 (2013)]. The former paper has been recently commented on by Vaidman [Phys. Rev. A 93, 036103 (2016)]. In this Reply we demonstrate that the comments are either invalid or, where valid, do not affect the results of our original paper.
