Track A6–A7: forward instrument and robust viability

Track A6–A7: forward instrument and robust viability · lines 1085–1103

At time $t$ , phase compensation gives projectors

Π_{\pm} = \frac{1}{2} (P \pm X_{ω t}), Π_{Ω} = ∣ Ω ⟩ ⟨ Ω ∣ .

Their selective maps are $ρ \mapsto Π_{x} ρ Π_{x}$ . A stochastic assignment matrix flips $+ \leftrightarrow -$ with probability $ε < 1/2$ , and independently erases with probability $1 - η$ . Preparation failure, loss, and erasure are recorded.

Use the score

f (-) = 1, f (+) = 0, f (Ω) = f (e) = f (p_{fail}) = 1/2.
