The Physics of Information
Christoph Adami
Abstract
Information theory is a statistical theory concerned with the relative state of detectors and physical systems. As a consequence, the classical framework of Shannon needs to be extended to deal with quantum detectors, possibly moving at relativistic speeds, conceivably within curved space-time. Considerable progress toward such a theory has been achieved in the last ten years, while much is still not understood. This review recapitulates some milestones along this road, and speculates about future ones.
