Quantum Goethals-Preparata Codes

Published 14 Jan 2008 in quant-ph, cs.IT, and math.IT | (0801.2150v1)

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.
