    "abstract": "Effective classicality of a property of a quantum system can be defined using\nredundancy of its record in the environment. This allows quantum physics to\napproximate the situation encountered in the classical world: The information\nabout a classical system can exist independently from its state. In quantum\ntheory this is no longer possible: In an isolated quantum system the state and\nthe information about it are inextricably linked, and any measurement may --\nand usually will -- reset that state. However, when the information about the\nstate of a quantum system is spread throughout the environment, it can be\ntreated (almost) as in classical physics.",
