Re-conceiving quantum theories in terms of information-theoretic constraints

Research output: Contribution to journalArticlepeer-review

Abstract

This paper examines Bub's interpretation of the foundational significance of the theorem of Clifton, Bub, and Halvorson (CBH) which characterizes quantum theories in terms of information-theoretic constraints. Bub argues that quantum theory must be re-conceived of as a principle theory of information where information is a new physical primitive, to the exclusion of hidden variable theories. I will argue, contrary to Bub, that the CBH theorem cannot be used to exclude hidden variables theories. Drawing inspiration from Bub, I sketch an alternative conception of quantum mechanics as a theory of information, but one which embraces all empirically equivalent quantum theories.
