The Operational Choi–Jamiołkowski Isomorphism
The Operational Choi–Jamiołkowski Isomorphism
In this article, I use an operational formulation of the Choi-Jamio\l{}kowski isomorphism to explore an approach to quantum mechanics in which the state is not the fundamental object. I first situate this project in the context of generalized probabilistic theories and argue that this framework may be understood as a …
