Dec 4, 2018 at 17:12	comment	added	Niel de Beaudrap		It looks as though the two maps are very similar. Have you considered describing them both in terms such as $\Lambda_p(\rho) := (1-p)\rho + p[ \sigma _z \rho \sigma_z] $, and considered what the effect of this map is on the coefficients of the density matrix?
