Efficient computation of the Nagaoka–Hayashi bound for multiparameter estimation with separable measurements
Abstract Finding the optimal attainable precisions in quantum multiparameter metrology is a non-trivial problem. One approach to tackling this problem involves the computation of bounds which impose limits on how accurately we can estimate certain physical quantities. One such bound is the Holevo Cr...
