Definition: Flagged erasure model

C6: implementation, model error, and radiation loss › A specified flagged whole-radiation erasure · lines 1546–1560

With probability $ℓ$ , independent of the message, all three accessible radiation carriers are lost and replaced by a fixed state. A classical flag reports the erasure:

N_{3, ℓ} (X) = (1 - ℓ) N_{3} (X) \otimes ∣ ok ⟩ ⟨ ok ∣ + ℓ tr (X) σ_{lost} \otimes ∣ lost ⟩ ⟨ lost ∣ .

This models complete flagged erasure, not arbitrary partial radiation loss.
