Abstract

In this paper, we propose a class of 1-generator quasi-twisted codes with special structures and investigate their application to construct ternary quantum codes. We discuss the algebraic structure of these 1-generator quasi-twisted codes and their dual codes. Moreover, sufficient conditions for these quasi-twisted codes to satisfy Hermitian self-orthogonality are given. Then, some ternary quantum codes exceeding the Gilbert-Varshamov bound are derived from such Hermitian self-orthogonal 1-generator quasi-twisted codes. In particular, sixteen quantum codes are new or have better parameters than those in the literatures, eight of which are obtained by the progapation rules.

New Binary Quantum Codes Derived from Quasi-Twisted Codes with Hermitian Inner Product

In this paper, a special class of two-generator quasi-twisted (QT) codes with index 2 will be presented. We explore the algebraic structure of the class of QT codes and the form of their Hermitian dual codes. A sufficient condition for self-orthogonality with Hermitian inner product is derived. Using the class of Hermitian self-orthogonal QT codes, we construct two new binary quantum codes [[70, 42, 7]]2, [[78, 30, 10]]2. According to Theorem 6 of Ref.[2], we further can get 9 new binary quantum codes. So a total of 11 new binary quantum codes are obtained and there are 10 quantum codes that can break the quantum Gilbert-Varshamov (GV) bound.

Quantum Codes Derived from One-Generator Quasi-Twisted Codes

Akram Saleh, M. Reza Soleymani

In this paper, we investigate one-generator quasi-twisted (QT) codes of index 3 over finite fields. Our objective is to characterize the dual code for this class of codes in terms of Hermitian inner product. We also establish sufficient conditions for self-orthogonality of these codes with respect to this inner product. As a result of our findings, we present examples of quantum error-correcting codes (QECCs) with good and optimal parameters derived from this family of QT codes.

An explicit construction of quantum codes from one-generator generalized quasi-cyclic codes

Yu Yao, Yuena Ma, Husheng Li +1 more

In this paper, we take advantage of a class of one-generator generalized quasi-cyclic (GQC) codes of index 2 to construct quantum error-correcting codes. By studying the form of Hermitian dual codes and their algebraic structure, we propose a sufficient condition for self-orthogonality of GQC codes with Hermitian inner product. By comparison, the quantum codes we constructed have better parameters than known codes.

Wenyu Han, Tongjiang Yan, Yuhua Sun +2 more

This paper investigates a class of 4-generator quasi-cyclic (QC) codes of index 4, together with their duals under the Euclidean, Hermitian, and symplectic inner products. We derive explicit generator characterizations of their dual codes and establish sufficient conditions for dual containment. Based on these structural results, several new quantum stabilizer codes and quantum synchronizable codes with desirable parameters are constructed.

Self-Orthogonal Twisted Generalized Reed-Solomon Codes and Their Application to Quantum Error-Correcting Codes

Yanxin Chen, Yanli Wang, Tongjiang Yan

In this paper, two classes of twisted generalized Reed-Solomon (TGRS) codes with multi-twists are studied. Firstly, some sufficient and necessary conditions for these codes to be self-orthogonal and self-dual are established. Then several explicit constructions of self-orthogonal and self-dual codes are presented, from which quantum stabilizer codes are further derived. Finally, some corresponding examples are given, especially that some of these codes are MDS, AMDS or NMDS and that some of the resulting quantum stabilizer codes are optimal, achieving the quantum Singleton bound.
