This paper explores geometric aspects of the inverse Choi-Jamio{\l}kowski isomorphism. It focuses on qubit channels corresponding to two-qubit circulant states that satisfy Bell's nonlocality condition. The main part is devoted to a characterization of nonlocality generating maps on the examples of both unital and non-unital maps. The advantage of this approach is that nonlocality of bipartite states can be controlled with a single parameter. The study reveals interesting geometric properties of quantum channels, contributing to the field of quantum nonlocality. |
