Quantum Codes Obtained from Constacyclic Codes
In this article, by using Hermitian construction, we obtain several new quantum codes and quantum MDS codes compare to the known codes from the constacyclic codes with only one q2-cyclotomic coset containing at least two consecutive integers with arbitrary difference r but fixed. This work is the generalization of the recent study on quantum codes from cyclic codes by La Guardia (Int. J. Theor. Phys. 56(8): 2479–2484, 2017) and from negacyclic codes by Gao and Wang (Int. J. Theor. Phys. 57(3): 682–686, 2018), respectively.
