Improvement of Ashikhmin-Litsyn-Tsfasman bound for quantum codes
Ryutaroh Matsumoto · IEEE Transactions on Information Theory · 2002
We improve performance of the asymptotically good quantum codes constructed by Ashikhmin, Litsyn and Tsfasman (see Phys. Rev. A, vol.63, no.3, p.032311, 2001), by using more rational points on algebraic curves.
