    "abstract": "In this paper and a companion paper, we attempt to systematically investigate\nthe possibility that the concept of information may enable a derivation of the\nquantum formalism from a set of physically comprehensible postulates. To do so,\nwe formulate an abstract experimental set-up and a set of assumptions based on\ngeneralizations of experimental facts that can be reasonably taken to be\nrepresentative of quantum phenomena, and on theoretical ideas and principles,\nand show that it is possible to deduce the quantum formalism. In particular, we\nshow that it is possible to derive the abstract quantum formalism for\nfinite-dimensional quantum systems and the formal relations, such as the\ncanonical commutation relationships and Dirac\u0027s Poisson Bracket rule, that are\nneeded to apply the abstract formalism to particular systems of interest. The\nconcept of information, via an information-theoretic invariance principle,\nplays a key role in the derivation, and gives rise to some of the central\nstructural features of the quantum formalism.",
