Title: New quantum mds constacylıc codes,
Abstract: This paper is devoted to the study of the construction of new quantum MDS
codes. Based on constacyclic codes over Fq2 , we derive four new families of
quantum MDS codes, one of which is an explicit generalization of the
construction given in Theorem 7 in [22]. We also extend the result of Theorem
3:3 given in [17].
