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

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.
