En07-B@1#def:leakage

For a density operator $σ$ on an output space, define

T_{σ} (X) = Tr (X) σ .

The complete residual leakage is

δ_{full} (V) = σ \in S (B) in f d_{⋄} (E, T_{σ}) .

For comparison, define the accessible featurelessness diagnostic

η_{R} (V) = ω \in S (R) in f d_{⋄} (N, T_{ω}) .

These are different quantities.
