the correspondence between linear maps on matrices and operators on a doubled space, under which complete positivity matches positivity of the Choi matrix.

In quantum information science, Choi-Jamiołkowski isomorphism refers to the correspondence between linear maps on matrices and operators on a doubled space, under which complete positivity matches positivity of the Choi matrix. This meaning comes from Choi (1975) in Linear Algebra and its Applications.[1]
