On the Importance of Interpretation in Quantum Physics. A Reply to Elise Crull

TL;DR

This paper critiques Crull's claim that decoherence alone can resolve measurement issues and advance quantum gravity and cosmology without interpretation, emphasizing the importance of interpretation in quantum physics.

Contribution

It clarifies misconceptions about decoherence and highlights the necessity of interpretation in understanding quantum phenomena.

Findings

Decoherence does not eliminate the need for interpretation.

Crull's claims about decoherence's sufficiency are mistaken.

Interpretation remains essential in quantum physics.

Abstract

Crull (2014) claims that by invoking decoherence it is possible (i) to obviate many ``fine grained'' issues often conflated under the common designation of measurement problem, and (ii) to make substantial progresses in the fields of quantum gravity and quantum cosmology, without any early incorporation of a particular interpretation in the quantum formalism. We point out that Crull is mistaken about decoherence and tacitly assumes some kind of interpretation of the quantum formalism.
