摘要

Self-orthogonal codes with dual distance three and quantum codes with distance three constructed from self-orthogonal codes over F_5 are discussed in this paper. Firstly, for given code length n ≥ 5, a [n,k _5 self-orthogonal code with minimal dimension k k and dual distance three is constructed. Secondly, for each n ≥ 5, two nested self-orthogonal codes with dual distance two and three are constructed, and consequently quantum code of length $$n$$ n and distance three is constructed via Steane construction. All of these quantum codes constructed via Steane construction are optimal or near optimal according to the quantum Hamming bound.
