    "abstract": "In this paper, we consider a simplified error-correcting problem: for a fixed\nencoding process, to find a cascade connected quantum channel such that the\nworst fidelity between the input and the output becomes maximum. With the use\nof the one-to-one parametrization of quantum channels, a procedure finding a\nsuboptimal error-correcting channel based on a semidefinite programming is\nproposed. The effectiveness of our method is verified by an example of the\nbit-flip channel decoding.",
