  This article outlines a novel interpretation of quantum theory: the Q-based
interpretation. The core idea underlying this interpretation, recently
suggested for quantum field theories by Drummond and Reid [2020], is to
interpret the phase space function Q -- a transform of the better known Wigner
function -- as a proper probability distribution, roughly analogous to the
probability distribution \rho in classical statistical mechanics.
  Here I motivate the Q-based interpretation, investigate whether it is
empirically adequate, and outline some of its key conceptual features. I argue
that the Q-based interpretation is attractive in that it promises having no
measurement problem, is conceptually parsimonious and has the potential to
apply elegantly to relativistic and field-theoretic contexts.
