In this paper, we consider a simplified error-correcting problem: for a fixedencoding process, to find a cascade connected quantum channel such that theworst fidelity between the input and the output becomes maximum. With the useof the one-to-one parametrization of quantum channels, a procedure finding asuboptimal error-correcting channel based on a semidefinite programming isproposed. The effectiveness of our method is verified by an example of thebit-flip channel decoding.Comment: 6 pages, no figure, Some notations differ from those in the PRA  versio
