Quantum Goethals-Preparata Codes
arXiv:0801.2150 · doi:10.1109/ISIT.2008.4594996
Abstract
We present a family of non-additive quantum codes based on Goethals and Preparata codes with parameters ((2^m,2^{2^m-5m+1},8)). The dimension of these codes is eight times higher than the dimension of the best known additive quantum codes of equal length and minimum distance.
