Abstract The distinctively quantum mechanical phenomena of interference and entanglement are explained. The theory of quantum mechanics that accounts for these phenomena is presented in its two forms: matrix mechanics and wave mechanics. It is argued that while these accounts have some of the superficial trappings of scientific explanation, they fail to provide an explanation in the sense of a description of the entities or properties responsible for the phenomena. In fact, the theory is remarkably silent regarding the physical states represented by the theory. The need for an interpretation of the quantum formalism—a way of understanding it as descriptive of the world—is defended.

In semiclassical mechanics one finds explanations of quantum phenomena that appeal to classical structures. These explanations are prima facie problematic insofar as the classical structures they appeal to do not exist. Here I defend the view that fictional structures can be genuinely explanatory by introducing a model-based account of scientific explanation. Applying this framework to the semiclassical phenomenon of wavefunction scarring, I argue that not only can the fictional classical trajectories explain certain aspects of this quantum phenomenon, but also that an explanation that does not make reference to these classical structures is, in a certain sense, deficient. 1.
