Neither Contextuality nor Nonlocality Admits Catalysts
Martti Karvonen
We show that the resource theory of contextuality does not admit catalysts, i.e., there are no correlations that can enable an otherwise impossible resource conversion and still be…
The Way of the Dagger
Martti Karvonen
A dagger category is a category equipped with a functorial way of reversing morphisms, i.e. a contravariant involutive identity-on-objects endofunctor. Dagger categories with addit…
A comonadic view of simulation and quantum resources
Samson Abramsky, Rui Soares Barbosa, Martti Karvonen +1
We study simulation and quantum resources in the setting of the sheaf-theoretic approach to contextuality and non-locality. Resources are viewed behaviourally, as empirical models.…
Reversible effects as inverse arrows
Chris Heunen, Robin Kaarsgaard, Martti Karvonen
Reversible computing models settings in which all processes can be reversed. Applications include low-power computing, quantum computing, and robotics. It is unclear how to represe…
Categories of Empirical Models
Martti Karvonen
A notion of morphism that is suitable for the sheaf-theoretic approach to contextuality is developed, resulting in a resource theory for contextuality. The key features involve usi…
