Abstract
A separable quantum channel acting on an n-partite system is a CPTP map that can be expressed as an operator sum representation of the form (Formula Present) where for each j the Kraus operatorKj has the form M1 M2 Mn. This definition is slightly different than what we used in our paper [1] since we also assume that all the matrices M1, Mn are full rank.We suggest to call this type of SEP operations SEP1.Hence, SEP1 SEP and SEP1 is clearly dense in SEP. With these notations, all the results of [1] hold if SEP is replaced with SEP1.
