Can you guys give me a concrete example of a completely positive map from M_m → M_n?

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

Could you please define it for us? I'm used to positive-definite maps, but not completely-positive ones.
