In this study, we obtain new classes of linear codes over Hurwitz integers
equipped with a new metric. We refer to the metric as Hurwitz metric. The codes
with respect to Hurwitz metric use in coded modu- lation schemes based on
quadrature amplitude modulation (QAM)-type constellations, for which neither
Hamming metric nor Lee metric. Also, we define decoding algorithms for these
codes when up to two coordinates of a transmitted code vector are effected by
error of arbitrary Hurwitz weight.Comment: 11 page
In this paper, some nonbinary quantum codes using classical codes over Gaussian integers are obtained. Also, some of our quantum codes are better than or comparable with those known before, (for instance $[[8,2,5]]_{4+i}$).
