A simple characterization of finite-dimensional quantum theory and Jordan-algebraic theories
Presented by Howard Barnum
We show that the quantum description of finite-dimensional systems, in terms of states, measurements, and probabilities of measurement outcomes, is characterized by four simple principles having an informational flavor. This characterization takes place within a much broader framework which conceives of states as effectively catalogues of probabilities for measurement results, and the space of states as an essentially arbitary compact convex set of such probability assignments. The background assumption of finite dimensionality the mathematics but may well be dispensable.
