Optimal Entanglement-Assisted Quantum Codes With Larger Minimum Distance
Wan Jiang, Shixin Zhu, Xiaojing Chen · IEEE Communications Letters · 2020
Entanglement-assisted quantum error-correcting code (EAQECC) is a new-type quantum code and can be constructed from arbitrary linear codes by sharing entangled states c in advance. In this letter, we explore a family of entanglement-assisted quantum error-correcting codes (EAQECCs) with length (q2- 1)/12 from negacyclic codes. Compared with known results in the literatures, our EAQECCs are new and have larger minimum distance.
