    • Choi Matrices of 2-positive Maps on Positive Semidefinite Matrices 

      Winda, C. A.; Okelo, N. B.; Omolo, Ongati (Asian Research Journal of Mathematics, 4/27/2020)
      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 ...

    • Completely Positive Map from M4(C) to M5(C) on Positive Semidefinite Matrices 

      Winda, C. A.; Okelo, N. B.; Ong’ati, Omolo (Journal of Mathematical Analysis and Modeling, 3/29/2022)
      Positive Maps Are Essential In the Description of Quantum Systems. However, Characterization Of The Structure Of The Set Of All Positive Maps Is A Challenge In Mathematics And Mathematical Physics. We Construct A Linear ...
