NEW OPTIMAL ASYMMETRIC QUANTUM CODES
Jianfa Qian, LINA ZHANG · Modern Physics Letters B · 2012
By using q2-ary cyclotomic cosets, we construct new asymmetric quantum codes with parameters [[q2+1, q2+1-2(k+i-2), (2k+3)/(2i+3)]]q2, where k and i are positive integers, and [Formula: see text]. The constructed asymmetric quantum codes are not covered by the codes available in the literature. Moreover, the constructed asymmetric quantum codes are optimal.
