Reply to Comment [axXiv:1610.07734] by L. Vaidman on "Particle path through a nested Mach-Zehnder interferometer" [R. B. Griffiths, Phys. Rev. A 94 (2016) 032115]

TL;DR

This paper defends the consistent histories approach to analyzing particle paths in a nested Mach-Zehnder interferometer, reaffirming its validity against criticisms and alternative methods not supported by standard quantum mechanics.

Contribution

It provides a rebuttal to criticisms of the consistent histories analysis, reinforcing its correctness in describing particle paths in quantum interferometry.

Findings

Consistent histories approach remains valid for particle path analysis.

Criticisms lack support from standard quantum mechanics.

Alternative methods are not supported by conventional theory.

Abstract

The correctness of the consistent histories analysis of weakly interacting probes, related to the path of a particle, is maintained against the criticisms in the Comment, and against the alternative approach described there, which receives no support from standard (textbook) quantum mechanics.
