Why this formula appears here
What the covariance also does, though, is forbid the radiation from leaking coherence between different eigenspaces of to an observer who has not independently fixed a frame. Kitaev, Mayers, and Preskill made the resource cost explicit: a superselection rule restricting accessible operations to those commuting with a group can be simulated away entirely if the two parties already share a suitable reference system, and cannot be worked around at all if they do not [ 11 ] . Absent such a shared frame, whatever the radiation reveals about g has to be extracted from the asymmetry of relative to the group — a quantity that scrambling, left to its own devices, does…
