In the present paper, the reduction of some proofs in \cite{Roga1} is presented. An entropic inequality for quantum state and bi-stochastic CP super-operators is conjectured.
Comments: 5 pages, LaTeX. A conjecture for some entropic inequality is added
Approximating projections by quantum operations
Reversibility conditions for quantum operations
Entropic inequalities as a necessary and sufficient condition to noncontextuality and locality
