    Description
Understanding how positivity of maps behaves under tensor products is linked to
several open problems in quantum information theory. In my talk, I will present
some recent results on how non-decomposable positive maps can arise from tensor
products and tensor powers of decomposable maps. The Choi-Jamio lkowski isomorphism is an indispensable tool in this line of research.
