Iterative procedure for computing accessible information in quantum communication
Original language description
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.
