On (θ, Θ)-cyclic codes and their applications in constructing QECCs
CoRR(2024)
Abstract
Let 𝔽_q be a finite field, where q is an odd prime power. Let
R=𝔽_q+u𝔽_q+v𝔽_q+uv𝔽_q with
u^2=u,v^2=v,uv=vu. In this paper, we study the algebraic structure of
(θ, Θ)-cyclic codes of block length (r,s ) over 𝔽_qR.
Specifically, we analyze the structure of these codes as left
R[x:Θ]-submodules of ℜ_r,s =
𝔽_q[x:θ]/⟨ x^r-1⟩×R[x:Θ]/⟨ x^s-1⟩. Our investigation involves
determining generator polynomials and minimal generating sets for this family
of codes. Further, we discuss the algebraic structure of separable codes. A
relationship between the generator polynomials of (θ, Θ)-cyclic
codes over 𝔽_qR and their duals is established. Moreover, we
calculate the generator polynomials of dual of (θ, Θ)-cyclic codes.
As an application of our study, we provide a construction of quantum
error-correcting codes (QECCs) from (θ, Θ)-cyclic codes of block
length (r,s) over 𝔽_qR. We support our theoretical results with
illustrative examples.
