Do neutrons disagree with photons about where they have been inside an interferometer?

TL;DR

Recent experiments with nested Mach-Zehnder interferometers suggest particles do not follow continuous trajectories inside the interferometers, challenging traditional notions of particle paths.

Contribution

The paper analyzes recent experiments and argues that they support a non-classical view of particle location, contrasting with claims of continuous trajectories.

Findings

Experiments support non-continuous particle localization.

Particles inside interferometers do not follow classical paths.

The analysis challenges traditional trajectory assumptions.

Abstract

Recent experiments with identically tuned nested Mach-Zehnder interferometers which attempted to observe the location of particles inside these interferometers are analyzed. In spite of claims to the contrary, it is argued that all experiments support the same surprising picture according to which the location of the particles inside the interferometers is not described by continuous trajectories.
