New EAQEC codes from LCP of codes over finite non-chain rings
In this paper, we first study the linear complementary pair (abbreviated to LCP) of codes over finite non-chain rings \(R_{u,v,q}={\mathbb {F}}_q+u{\mathbb {F}}_q+ v{\mathbb {F}}_q+uv{\mathbb {F}}_q\) with \(u^2=u,v^2=v\). Then we provide a method of constructing entanglement-assisted quantum error-correcting (abbreviated to EAQEC) codes from an LCP of codes of length n over \(R_{u,v,q}\) using CSS. To enrich the variety of available EAQEC codes, some new EAQEC codes are given in the sense that their parameters are different from all the previous constructions.
