Separate memoryless loss–dephasing model

Track A1: carrier, matched branches, and exact dynamics › Separate memoryless loss–dephasing model · lines 451–460

For a code Hamiltonian $ℏ h$ , the conditional state obeys

S ˙ = - i [h, S] + (γ + R) (Δ S - S) .

The explicit exponential witness requires $[h, Z] = 0$ . The vacuum-plus-code architecture is motivated by Em04-A CheungEm04A; its biological matching is not inherited.
