contents In any given experimental scenario, the rules of quantum theory provide statistical distributions that the observed outcomes are expected to follow. The set formed by all these distributions contains the imprint of quantum theory, capturing some of its core properties. So far, only partial descriptions have been known for this set, even in the simplest scenarios. Here, we obtain the analytical description of a complete set of quantum statistics in terms of extremal points. This is made possible by finding all bipartite quantum states and pairs of binary measurements which can be self-tested, i.e. identified from statistics only. Our description provides a direct insight into the properties and limitations of quantum theory. These are not expressed in terms of Hilbert spaces, but rather directly in terms of measurement observation statistics.
