### Abstract

According to Niels Bohr "*If you can fathom quantum mechanics without getting dizzy, then you don’t understand any of it.*" Logic is the art of organizing the elements of the discourse so that the conclusions clearly and obviously follow from the premisses.

Logical studies of quantum mechanics took off with the landmark 1936 quantum logic paper of Birkhoff and von Neumann, contemporary with the discovery of the foundations of computer science by Curry, Church and Turing. The needs of quantum based computing, and the discovery of the tight relation between computing and logic highlighted by Curry-Howard correspondence motivate a novel constructive logic based approach to some fundamental experiments of quantum mechanics. More specifically, we address single photon self-interference experiments and the related wave-particle duality paradox.
