Query: Density Hypercubes, Higher Order Interference and Hyper-Decoherence: a
  Categorical Approach   In this work, we use the recently introduced double-dilation construction by
Zwart and Coecke to construct a new categorical probabilistic theory of density
hypercubes. By considering multi-slit experiments, we show that the theory
displays higher-order interference of order up to fourth. We also show that the
theory possesses hyperdecoherence maps, which can be used to recover quantum
theory in the Karoubi envelope.
