The passage around this formula

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 ρF(g)\rho_F(g) , pϵ(F)p_\epsilon(F) , or Rϵ,δR_{\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…
