Abstract：In this paper, constacyclic codes over the finite field GF(q2) of length (q2m-1)/(q2-1) are studied.
A sufficient and necessary condition for a class of constacyclic codes to be Hermitian dual-containing codes is given, and the parameters of this class of constacyclic codes are determined. Using Hermitian construction, the obtained quantum codes, are better than the parameters of quantum BCH codes.
