Quantum codes are obtained through (1 - 2 nu omega)-constacyclic codes over a finite non-chain ring Zm + nu Zm + omega Zm + nu omega Zm with nu 2 = nu omega 2 = omega and , nu 2 omega 2 = nu omega . (1 - 2 nu omega)-constacyclic codes over the ring Zm + nu Zm + omega Zm + nu omega Zm are decomposed into two codes over the ring Zm in order to obtain the parameters for the corresponding quantum codes over the ring Zm. Some examples of quantum codes are also provided to verify the results. 收起
