The purpose of this article is threefold. Firstly, it aims to present, in an educational and nontechnical fashion, the main ideas at the basis of Aerts’ creationdiscovery view and hidden measurement approach: a fundamental explanatory framework whose importance, in this author’s view, has been seriously underappreciated by the physics community, despite its success in clarifying many conceptual challenges of quantum physics. Secondly, it aims to introduce a new quantum machine—that we call the δ quantum machine—which is able to reproduce the transmission and reflection probabilities of a onedimensional quantum scattering process by a Dirac deltafunction potential. The machine is used not only to demonstrate the pertinence of the above mentioned explanatory framework, in the general description of physical systems, but also to illustrate (in the spirit of Aerts’ ∊model) the origin of classical and quantum structures, by revealing the existence of processes which are neither classical nor quantum, but irreducibly intermediate. We do this by explicitly introducing what we call the kmodel and by proving that its processes cannot be modelized by a classical or quantum scattering system. The third purpose of this work is to exploit the powerful metaphor provided by our quantum machine, to investigate the intimate relation between the concept of potentiality and the notion of nonspatiality, that we characterize in precise terms, introducing for this the new concept of processactuality.
