  Foundational investigations in quantum mechanics, both experimental and
theoretical, gave birth to the field of quantum information science.
Nevertheless, the foundations of quantum mechanics themselves remain hotly
debated in the scientific community, and no consensus on essential questions
has been reached. Here, we present the results of a poll carried out among 33
participants of a conference on the foundations of quantum mechanics. The
participants completed a questionnaire containing 16 multiple-choice questions
probing opinions on quantum-foundational issues. Participants included
physicists, philosophers, and mathematicians. We describe our findings,
identify commonly held views, and determine strong, medium, and weak
correlations between the answers. Our study provides a unique snapshot of
current views in the field of quantum foundations, as well as an analysis of
the relationships between these views.
