    "abstract": "The logical structure of Quantum Mechanics (QM) and its relation to other\nfundamental principles of Nature has been for decades a subject of intensive\nresearch. In particular, the question whether the dynamical axiom of QM can be\nderived from other principles has been often considered. In this contribution,\nwe show that unitary evolutions arise as a consequences of demanding\npreservation of entropy in the evolution of a single pure quantum system, and\npreservation of entanglement in the evolution of composite quantum systems.",
