Masaaki Harada · International Journal of Quantum Information · 2019
We establish the existence of optimal entanglement-assisted quantum [Formula: see text] codes for [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. These codes are obtained from quaternary Hermitian linear complementary dual codes. We also give some observations on the largest minimum weights.
