We establish the existence of optimal maximal entanglement entanglement-assisted quantum [[n,k,d;n-k]] codes for (n,k,d)=(14,6,7), (15,7,7), (17,6,9), (17,7,8), (19,7,9) and (20,7,10). These codes are obtained from quaternary Hermitian linear complementary dual codes. We also give some observation on the largest minimum weights.
