Pure quantum interpretations are not viable

TL;DR

Pure quantum interpretations that discard the classical aspect without introducing new structure are shown to be unviable due to non-uniqueness issues with canonical operators.

Contribution

The paper demonstrates the non-viability of pure quantum interpretations by proving a non-uniqueness result for canonical operators.

Findings

Pure interpretations lack a unique set of canonical operators.

Non-uniqueness undermines the consistency of pure interpretations.

Results challenge the viability of interpretations that omit classical elements.

Abstract

Pure interpretations of quantum theory, which reject the classical part of the Copenhagen interpretation without adding new structure to it's quantum part, are not viable. This is a consequence of a non-uniqueness result for the canonical operators.
