Hawk01-B@1#eq:dephasing

Let all emitted blocks be measured destructively in their fixed occupation/rail bases. The complete record retains key, transfer time, vacuum, and saturation or loss flags. No selected branch is omitted.

Define logical dephasing

Δ_{Z} (Y) = i = 0 \sum^{d - 1} ∣ i ⟩ ⟨ i ∣ Y ∣ i ⟩ ⟨ i ∣ .
