SOMIM: An open-source program code for the numerical Search for Optimal Measurements by an Iterative Method
Abstract
SOMIM is an open-source code that implements a Search for Optimal Measurements by using an Iterative Method. For a given set of statistical operators, SOMIM finds the POVMs that maximizes the accessed information, and thus determines the accessible information and one or all of the POVMs that retrieve it. The maximization procedure is a steepest-ascent method that follows the gradient in the POVM space, and uses conjugate gradients for speed-up.
