  Quasi-twisted codes are used here as the classical ingredients in the
so-called Construction X for quantum error-control codes. The construction
utilizes nearly self-orthogonal codes to design quantum stabilizer codes. We
expand the choices of the inner product to also cover the symplectic and
trace-symplectic inner products, in addition to the original Hermitian one. A
refined lower bound on the minimum distance of the resulting quantum codes is
established and illustrated. We report numerous record breaking quantum codes
from our randomized search for inclusion in the updated online database.
