The approach is based on a general framework, which allows one to address a large class of physical theories which share basic information-theoretic features. We first illustrate two very primitive features, expressed by the axioms of causality and purity-preservation, which are satisfied by both classical and quantum theory. We then discuss the axiom of purification, which expresses a strong version of the Conservation of Information and captures the core of a vast number of protocols in quantum information. Purification is a highly non-classical feature and leads directly to the emergence of entanglement at the purely conceptual level, without any reference to the superposition principle. Supplemented by a few additional requirements, satisfied by classical and quantum theory, it provides a complete axiomatic characterization of quantum theory for finite dimensional systems.", "revisions": [ { "version": "v1", "updated": "2014-11-11T08:14:31.000Z" } ], "analyses": { "keywords": [ "quantum mechanics", "quantum theory", "conservation", "foundations", "share basic information-theoretic features" ], "tags": [ "conference paper" ], "publication": { "doi": "10.1051/epjconf/20159503003" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1327765, "adsabs": "2015EPJWC..9503003C" } } }
