Quantum codes constructed from cyclic codes over the ring š½_q+vš½_q+v^2š½_q+v^3š½_q+v^4š½_q
In this article, we investigate properties of cyclic codes over a finite non-chain ring š½_q+vš½_q+v^2š½_q+v^3š½_q+v^4š½_q, where q=p^r, r is a positive integer, p is an odd prime, 4 | (p-1), and v^5=v. As an application, we construct several quantum error correcting codes over the finite field š½_q.
