| Popis: | A recent method to certify the classical capacity of quantum communication channels is applied for general damping channels in finite dimension. The method compares the mutual information obtained by coding on the computational and a Fourier basis, which can be obtained by just two local measurement settings and classical optimization. The results for large representative classes of different damping structures are presented. 9 pages, 15 figures. Improved version and new figures |
