Choi-defined resource theories
Elia Zanoni, Carlo Maria Scandolo · Physical Review A · 2025
Many resource theories share an interesting property: An operation is free if and only if its renormalized Choi matrix is a free state. In this article, we refer to resource theories exhibiting this property as Choi-defined resource theories. We demonstrate how and under what conditions one can construct a Choi-defined resource theory, and we prove that when such a construction is possible, the free operations are all and only the completely resource-nongenerating operations. Moreover, we examine resource measures, a complete family of monotones, and conversion distances in such resource theories.
