# Characterization of Maps on Positive Semidefinite Choi Matrices

## Keywords:

Choi matrix, completely positive, Positive map## Abstract

Several investigations have been done on positive maps on their algebraic structures with more emphasis on completely positive maps. In this study, we have described the structure of the Choi matrices for 2-positive maps on positive semidefinite matrices and the conditions for complete positivity of positive linear maps from n to n+1. The motivation behind these objectives is work done by Majewski and Marciniak on the structure of positive maps ф from M_{n} to M_{n} + 1(2 ≥ 2) between matrix algebras.
