Quantum codes from codes over Gaussian integers with respect to the Mannheim metric
Mehmet Özen, Murat Güzeltepe · Quantum Information and Computation · 2012
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 $[[8,2,5]]_{4+i}$).
