Proposition: The wholly classical bound is not this null's bound

Environmental memory and the required refusal › A different null for an already quantum carrier · lines 1778–1793 · proof included or linked

Psy04-B@1#prop:environmentbound

If $N_{2, 1, U}$ admits the present code and imposes no compulsory intermediate disturbance, then

P \in N_{2, 1, U} sup E_{P} s \geq \frac{1}{2} + \frac{1}{2 2} .

Thus $3/4$ is not an environmental-memory exclusion bound for this class.

Proof. A one-value environmental alphabet is trivial. The Markovian winning qubit process belongs to the null.
