New quantum MDS code from constacyclic codes
In recent years, there have been intensive activities in the area of constructing quantum maximum distance separable (MDS for short) codes from constacyclic MDS codes through the Hermitian construction. In this paper, a new class of quantum MDS code is constructed, which extends the result of [Theorems 3.14 3.15, Kai, X. Zhu, S. and Li, P. IEEE Trans. on Inf. Theory, 60(4) 2014, 2080 2086] in the sense that our quantum MDS code has bigger minimum distance.
