SeCQC: An open-source program code for the numerical Search for the classical Capacity of Quantum Channels
Abstract
SeCQC is an open-source program code which implements a Numerical Search for the classical Capacity of Quantum Channels (SeCQC) by using an iterative method. Given a quantum channel, SeCQC finds the statistical operators and POVM outcomes that maximize the accessible information, and thus determines the classical capacity of the quantum channel. The optimization procedure is realized by using a steepest-ascent method that fol- lows the gradient in the POVM space, and also uses conjugate gradients for speed-up.
