$R_{\epsilon,\delta}(g)$

Why this formula appears here

A fourth rival is more corrosive than the first three because it does not challenge the definitions; it challenges whether they require quantum mechanics at all. Nothing in $\rho_F(g)$ , $p_\epsilon(F)$ , or $R_{\epsilon,\delta}$ forces the fragments to be quantum-correlated in a way a classical broadcast could not reproduce. Replace the spin- j rotor with a single classical variable drawn once from the same prior and handed to N independent classical sensors, each corrupted by rotation-equivariant noise tuned to match the quantum construction’s per-fragment error rate. That model satisfies the covariance requirement, clears the blind-guess bound, and can be dialed to any $R_{\epsilon,\delta}(g)$ …
