摘 要:Let R be the ring ■2m+u■2m,where u2=*** introduce a Gray map from R to ■2~2 m and study(1+u)-constacyclic codes over *** is proved that the image of a(1+u)-constacyclic code length n over R under the Gray map is a distance-invariant binary quasicyclic code of index m and length 2 *** also prove that every code of length 2 mn which is the Gray image of cyclic codes over R of length n is permutation equivalent to a binary quasi-cyclic code of index ***,a family of quantum error-correcting codes obtained from the Calderbank-Shor-Steane(CSS) construction applied to(1+u)-constacyclic codes over R.
