Even quantum pigeons may thrive together. A note on 'the quantum pigeonhole principle'

TL;DR

This paper critically examines claims about the quantum pigeonhole principle, highlighting ambiguities in correlation definitions and questioning the significance of initial experiments, thus challenging the original conclusions.

Contribution

It provides a critical analysis of the quantum pigeonhole principle, emphasizing the importance of correlation definitions and scrutinizing experimental claims.

Findings

Correlation definitions affect conclusions

Initial experiments have limited implications

Main claims may be premature

Abstract

The findings in the paper 'The quantum pigeonhole principle and the nature of quantum correlations', (arXiv 1407.3194), by Aharonov, Colombo, Popescu, Sabadini, Struppa and Tollaksen are scrutinized. I argue that some of the conclusions in the paper are ambiguous in the sense that they depend on the precise way one defines correlations, and that the 'first experiments' the authors suggest has little if any bearing on their main theses. The far-reaching conclusions the authors reach seems, therefore, premature.
