Why this formula appears here
An estimator is generated by a positive-operator-valued measure on the fragment. Covariance requires that rotating the encoded state by h rotates the distribution of estimates by the same group action. In schematic form, . Group-covariant estimation is established machinery. Bagan, Baig, and Muñoz-Tapia derived optimal strategies for transmitting and estimating Cartesian frames with finite spin systems [ 5 ] . Chiribella, D’Ariano, and Sacchi treated optimal estimation of group transformations under a class of invariant cost functions and connected the construction directly to reference-frame transmission [ 6 ] . The novelty proposed here is not the covariant…
