Optimal data processing for quantum measurements
arXiv:quant-ph/0610058 · doi:10.1103/PhysRevLett.98.020403
Abstract
We consider the general measurement scenario in which the ensemble average of an operator is determined via suitable data-processing of the outcomes of a quantum measurement described by a POVM. We determine the optimal processing that minimizes the statistical error of the estimation.
