The Choi–Jamiołkowski isomorphism is a mathematical correspondence between linear operators on quantum states and certain types of bipartite quantum states. Specifically, it establishes a connection between completely positive maps and density operators in finite dimensions, which is crucial in the context of quantum physics and quantum information theory.
