Quantum fields are not fields. Comment on "There are no particles, there are only fields," by Art Hobson [Am. J. Phys. 81(3), 211-223 (2013)]

TL;DR

This paper critiques Hobson's claim that quantum fields are just like particles, arguing that replacing particles with fields does not resolve quantum interpretational issues, emphasizing the conceptual distinction remains important.

Contribution

It provides a critical analysis showing that quantum fields are not equivalent to classical fields and that ontology shifts do not resolve foundational quantum problems.

Findings

Quantum fields are not equivalent to classical fields.

Replacing particles with fields does not solve interpretational issues.

The conceptual distinction between particles and fields remains significant.

Abstract

We comment on a recent paper by Hobson, explaining that quantum "fields" are no more fields than quantum "particles" are particles, so that the replacement of a particle ontology by an all-field ontology cannot solve the typical interpretational problems of quantum mechanics.
