| Feb 1, 2018 at 20:47 | comment | added | lcv | Yes. Incidentally $\mathbf{T}$ is completely positive. | |

| Feb 1, 2018 at 16:45 | comment | added | Student | I think that in order to get $$\big\|\sum_{j\in J}A_j^*LA_j\big\|\le \big\|\sum_{j\in J}A_j^*A_j\big\|\ \|L\|\ ,$$ the operator $L$ should be positive not $L\in \mathcal{L}_{sym}(H)$. | |
