u-Constacyclic codes over F-p + uF(p) and their applications of constructing new non-binary quantum codes

摘要

Structural properties of u-constacyclic codes over the ring F-p + uF(p) are given, where p is an odd prime and u(2) = 1. Under a special Gray map from F-p + uF(p) to F-p(2), some new non-binary quantum codes are obtained by this class of constacyclic codes.
