Abstract
In this paper we construct a 2-positive map fromM4(C) toM5(C) and state the conditions under which the map is positive and completely positive (copositivity of positive). The construction allows us to create a decomposable map, where the Choi matrix of complete positivity is equal to the Choi matrix of complete copositivity.
