We consider the relation between observables and states for all internal dimensions at once. Building on operator systems, we derive results for other notions of positivity.
With Tim Netzer and Mirte van der Eyden, many beautiful drawings. To appear in J. Math. Anal.

Beyond Operator Systems
Operator systems connect operator algebra, free semialgebraic geometry and quantum information theory. In this work we generalize operator systems and many of their theorems. While positive semidefini...

The internal dimension of the system is essentially the number of independent answers it can give. I always found the dimension an ‘intimate’ property of the system, because one can only lower bound it.
