Abstract
Constructor Theory, a new fundamental theory of physics where counterfactual properties are taken as fundamental, solves the riddle of how information, despite its abstraction-like properties, can be physical: it roots the current theories of computation and information in fundamental physics and expresses exactly the link between quantum and classical information. As Eddington envisaged, incorporating counterfactuals into fundamental physics can have far-reaching consequences and expand the domain of applicability of our physical theories.
