Some good quantum twisted codes

I give here some examples of good GF(q)-linear q²-ary quantum twisted codes for

q=2, length up to 1000

q=3, length up to 1000

q=4, length up to 1000

q=5, length up to 1000

q=7, length up to 1000

q=8, length up to 1000

q=9, length up to 1000

eventually standard lengthening was used. The distance was found by the BCH-bound. For more details and definitions see quantum twisted codes.

For nonbinary quantum codes see also, as a reference, the paper of A. Ashikhmin and E. Knill (LANL preprint, quant-ph/0005008).
