Destructive readout of the flagged output

An explicit conserving transfer schedule › Destructive readout of the flagged output · lines 1154–1165

Measure the accessible occupied basis ${J ∣ i ⟩}$ and its vacant flag. Complete this to a basis on unused accessible subspaces. The resulting classical channel is

M_{q} (X) = (1 - q) i \sum ⟨ i ∣ X ∣ i ⟩ ∣ i ⟩ ⟨ i ∣_{Y} + q Tr (X) ∣ e ⟩ ⟨ e ∣_{Y} .
