摘要
In this paper, we present three new classes of q-ary quantum MDS codes utilizing generalized Reed-Solomon codes satisfying Hermitian self-orthogonal property. Among our constructions, the minimum distance of some q-ary quantum MDS codes can be bigger than q/2 + 1. Comparing to previous known constructions, the lengths of codes in our constructions are more flexible.
