Asymptotically good quantum codes exceeding the Ashikhmin-Litsyn-Tsfasman bound
Hao Chen, San Ling, Chaoping Xing · IEEE Transactions on Information Theory · 2001
It is known that quantum error correction can be achieved using classical binary codes or additive codes over F/sub 4/. Asymptotically good quantum codes have been constructed from algebraic-geometry codes and a bound on (/spl delta/, R) was computed from the Tsfasman-Vladut-Zink bound of the theory of classical algebraic-geometry codes. In this correspondence, by the use of a concatenation technique we construct a family of asymptotically good quantum codes exceeding the bound in a small interval.
