Idea

The theorem of (Alfsen-Shultz 78) says that two C*-algebras have isomorphic state spaces precisely if as Jordan algebras they are isomorphic.

This is to some extent a Jordan algebra-analog of the Gelfand-Naimark theorem.

Other theorems about the foundations and interpretation of quantum mechanics include:
