  We use Khovanov homology to define families of LDPC quantum error-correcting
codes: unknot codes with asymptotical parameters
[[3^(2l+1)/sqrt(8{\pi}l);1;2^l]]; unlink codes with asymptotical parameters
[[sqrt(2/2{\pi}l)6^l;2^l;2^l]] and (2,l)-torus link codes with asymptotical
parameters [[n;1;d_n]] where d_n>\sqrt(n)/1.62.
