Jingjie Lv, Ruihu Li, Qiang Fu · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2019
In this paper, we consider a wide family of λ-quasi-twisted (λ-QT) codes of index 2 and provide a bound on the minimum Hamming distance. Moreover, we give a sufficient condition for dual containing with respect to Hermitian inner product of these involved codes. As an application, some good stabilizer quantum codes over small finite fields 𝔽2 or 𝔽3 are obtained from the class of λ-QT codes.
