Query: Quantum codes from codes over Gaussian integers with respect to the
  Mannheim metric   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).
