Comments on "Objectification of classical properties induced by quantum vacuum fluctuations"

TL;DR

The paper critiques a proposal suggesting vacuum fluctuations cause decoherence in atomic systems, arguing that standard quantum electrodynamics does not support this effect without deliberate switching of interactions.

Contribution

It clarifies that radiative corrections in quantum electrodynamics do not induce decoherence unless interactions are artificially toggled.

Findings

Radiative corrections do not cause decoherence in unexcited atoms.

Decoherence requires deliberate switching of vacuum interactions.

Standard QED does not support Santos's proposal.

Abstract

We argue that in standard quantum electrodynamics radiative corrections do not lead to decoherence of unexcited atomic systems. The proposal of Santos relies upon deliberate switching on and off the vacuum interactions.
