Aug 26, 2013 at 7:08 comment added Urs Schreiber The types in the internal logic of a Bohr topos (ncatlab.org/nlab/show/Bohr%20topos) associated with a $C^\ast$-algebra are the "presheaves on classical contexts", hence all things that can be "probed" by commuting subalgebras of the given $C^\ast$-algebra of quantum operators. This is, so far, a proposal only for how to formulate phase spaces of quantum states in topos theory. For a synthetic formulation of quantum field theory comprehensively in higher toposes see ncatlab.org/schreiber/show/Synthetic+Quantum+Field+Theory

Aug 26, 2013 at 2:47 comment added François G. Dorais It's unclear what you are asking. Are you asking for the internal logic of a specific topos? A family of topoi? All topoi? Do you have one paper in mind or do you expect us to read them all?
