Quantum systems can and have been used to develop algorithms and communication protocols that outperform their classical counterparts. The advantages provided by quantum systems are studied within the framework of quantum resource theories, in which quantum states and operations are divided into free and resourceful. Many of these resource theories share an interesting property: an operation is free if and only if its image under an isomorphism known as the Choi isomorphism is a free state. We refer to resource theories exhibiting this property as Choi-defined resource theories. In this talk, I will present the mathematical framework used in quantum information and introduce quantum resource theories. Furthermore, I will define Choi-defined resource theories and demonstrate how and under what conditions one can construct them. Lastly, I will present some properties shared by all Choi-defined resource theories.

This is a special seminar for the Theory groups of High Energy, Statistical Physics and Quantum Information.
