The passage around this formula
…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 the quantum calculation…
