Quantum codes from affine variety codes and their subfield-subcodes (1403.4060v2)
Published 17 Mar 2014 in cs.IT and math.IT
Abstract: We use affine variety codes and their subfield-subcodes for obtaining quantum stabilizer codes via the CSS code construction. With this procedure, we get codes with good parameters and a code whose parameters exceed the CSS quantum Gilbert-Varshamov bound given by Feng and Ma.
