Quantum codes from affine variety codes and their subfield-subcodes
We use affine variety codes and their subfield-subcodes to obtain quantum stabilizer codes via the CSS code construction. With this procedure we get codes with good parameters, some of them exceeding the CSS quantum GilbertVarshamov bound given by Feng and Ma.
