Abstract and Keywords

Abstract: In this paper, sufficient conditions for the images of two classes of cyclic codes to be Hermitian self-orthogonal are given. Two new classes of quantum codes are obtained from the Hermitian self-orthogonal image of cyclic codes by using Hermitian construction. These new quantum codes obtained have better parameters than the known ones with same lengths such as larger minimum distance or higher code rate.

Keywords: quantum error-correcting codes; cyclic codes; Hermitian self-orthogonal; Hermitian construction
