| Oct 26, 2017 at 7:36 | comment | added | Niel de Beaudrap | @YemonChoi: (a) if $\Psi$ is a right-inverse of a unital map, is it not also ipso facto unital? (b) I am very sure that I do not want to restrict to trace-preserving unital maps --- I have the 'trace' tag only because I'm aware that trace-preservation is the dual property to unitality, so there is an equivalent version of this question involving trace-preserving maps which may not be unital, and their left inverses. | |

Revised to focus on the case I'm principally interested in, in particular to exclude the case of the transpose

Erratum (trace preserving --> unital)

Fixed incorrect norm in equation (the result of a question revision)
