In this short paper, we consider the non-binary quantum codes construction from a class of linear codes, which are not self-orthogonal over finite fields. As the computational results, new quantum codes

In this paper, we show that any λ-constacyclic code over F q m is a λ-constacyclic code over F q under some special maps. Moreover, we show that the images of these λ−constacyclic codes can be put into the concatenated form. INDEX TERMS λ-constacyclic codes, images of maps, concatenated codes.
