The passage around this formula

…problem of the kind Bartlett, Rudolph, and Spekkens formalize was ever posed to the circuit [ 9 ] . The honest parameter range this construction can claim, then, is narrow and asymmetric on purpose: the mechanism behind tLt_L has a laboratory analogue at the scale of a handful of trapped ions, verified by an actual measured teleportation fidelity; the mechanism behind tGt_G has none. Every number attached to tGt_G in this article — the toy accumulation law, the per-quantum Fisher information f1f_1 , the crossover…
