  Measure theory is used in physics, not just to capture classical probability,
but also to quantify the number of states. In previous works, we found that
state quantification plays a foundational role in classical mechanics, and
therefore, we set ourselves to construct the quantum equivalent of the
Liouville measure. Unlike the classical counterpart, this quantized measure is
non-additive and has a unitary lower bound (i.e. no set of states can have less
than one state). Conversely, requiring that state quantification is finite for
finite continuous regions and that each state counts as one already implies
non-additivity, which in turn implies the failure of classical theory. In this
article we show these preliminary results and outline a new line of inquiry
that may provide a different insight into the foundations of quantum theory.
Additionally, this new approach may prove to be useful to those interested in a
quantized theory of space-time, as we believe this requires a quantized measure
for the quantification of the independent degrees of freedom.
