Definition: Reference-preserving recovery error

Sequential models and recovery criteria · lines 278–289

For a decoder $D_{t} : E D_{\leq t} \to M$ , define

ϵ (D_{t}, t) = d_{⋄} (D_{t} N_{t}, id_{M}), d_{⋄} (Φ, Ψ) = \frac{1}{2} ∥ Φ - Ψ ∥_{⋄} .

The diamond norm includes arbitrary entanglement with an external reference Watrous (Chapters 2–3).
