    "abstract": "Consider a joint quantum state of a system and its environment. A measurement\non the environment induces a decomposition of the system state. Using\nalgorithmic information theory, we define the preparation information of a pure\nor mixed state in a given decomposition. We then define an optimal\ndecomposition as a decomposition for which the average preparation information\nis minimal. The average preparation information for an optimal decomposition\ncharacterizes the system-environment correlations. We discuss properties and\napplications of the concepts introduced above and give several examples.",
