Vaidmans nested MZI, again

TL;DR

This paper critiques Vaidman's weak value analysis of a particle's path in a nested Mach-Zehnder interferometer, arguing that weak measurements disturb the system and thus cannot reliably indicate the undisturbed path.

Contribution

It offers additional arguments using sequential weak values to challenge the validity of weak value analysis in the nested Mach-Zehnder interferometer.

Findings

Weak measurements disturb the system significantly.

Projector weak values do not reliably represent the undisturbed system.

Sequential weak values reinforce the critique of weak value analysis.

Abstract

I provide additional arguments for refuting Vaidmans weak value analysis of the path of a particle in a nested Mach-Zehnder interferometer. The argument uses sequential weak values to supplement my previous analysis according to which even weak measurements disturb the system to such an extent that projector weak values cannot be considered representative for the undisturbed system.
