"We present an iterative algorithm that finds the optimal measurement for extracting the accessible information in any quantum communication scenario. The maximization is achieved by a steepest-ascent approach toward the extremal point, following the gradient uphill in sufficiently small steps. We apply it to a simple ad hoc example, as well as to a problem with a bearing on the security of a tomographic protocol for quantum key distribution."@en . . "525793" . "1"^^ .
