RT info:eu-repo/semantics/article T1 Quasi-cyclic constructions of quantum codes A1 Galindo, Carlos A1 Hernando, Fernando A1 Matsumoto, Ryutaroh K1 Quasi-cyclic codes K1 Códigos cuasicíclicos K1 Quantum codes K1 Códigos cuánticos K1 Algebraic constructions K1 Construcciones algebráicas AB We give sufficient conditions for self-orthogonality with respect to symplectic, Euclidean and Hermitian inner products of a wide family of quasi-cyclic codes of index two. We provide lower bounds for the symplectic weight and the minimum distance of the involved codes. Supported in the previous results, we show algebraic constructions of good quantum codes and determine their parameters.
