In the present study, we define cyclic codes over the commutative principal ideal ring F2 ? (F2 + vF2) with v2 = v and obtain some results on cyclic codes over F2 ? (F2 + vF2). We also investigate the dual of a cyclic code over F2 ? (F2 + vF2) depending on two inner products. We determine a generator polynomial of cyclic codes and give the calculation of the number of cyclic codes over F2 ? (F2 + vF2). Furthermore, we show that the Gray images of a cyclic code over F2 ? (F2 + vF2) of length n are binary quasi-cyclic codes of length 3n and of index 3. We find numerous binary codes as Gray images of cyclic codes over F2 ? (F2 + vF2) and tabulate the optimal ones. Moreover, we show that it is possible to obtain binary quantum error-correcting codes (QECCs) from cyclic codes over F2 ? (F2 + vF2).
Let
R=F2+uF2+u2F2 be a non-chain finite commutative ring, where
u3=u. In this paper, we mainly study the construction of quantum codes from cyclic codes over
R. We obtained self-orthogonal codes over
F2 as gray images of linear and cyclic codes over
R. The parameters of quantum codes which are obtained from cyclic code over
R are discussed.
