    "abstract": "Niels Bohr wrote: \"There is no quantum world. There is only an abstract\nquantum physical description. It is wrong to think that the task of physics is\nto find out how Nature is. Physics concerns what we can say about Nature.\" In\nan analogous way, von Weizsaecker suggested that the notion of the elementary\nalternative, the \"Ur\", should play a pivotal role when constructing physics.\nBoth approaches suggest that the concept of information should play an\nessential role in the foundations of any scientific description of Nature. We\nshow that if, in our description of Nature, we use one definite proposition per\nelementary constituent of Nature, some of the essential characteristics of\nquantum physics, such as the irreducible randomness of individual events,\nquantum complementary and quantum entanglement, arise in a natural way. Then\nquantum physics is an elementary theory of information.",
