The entanglement-assisted stabilizer formalism can transform arbitrary classical linear codes into entanglement-assisted quantum error correcting codes (EAQECCs). In this work, we construct some new entanglement-assisted quantum MDS (EAQMDS) codes with length n=q^2+1/5 from cyclic codes. Compared with all the previously known parameters with the same length, all of them have flexible parameters and larger minimum distance.
