New quantum codes from constacyclic codes over finite chain rings

Yongsheng Tang, Ting Yao, Heqian Xu +1

Let $R$ be the finite chain ring $F_{p^{2 m}} + u F_{p^{2 m}}$ , where $F_{p^{2 m}}$ is the finite field with $p^{2 m}$ elements, $p$ is a prime, $m$ is a non-…

A note on the Singleton bounds for codes over finite rings

Yongsheng Tang, Heqian Xu, Zhonghua Sun

In this paper, we give a notation on the Singleton bounds for linear codes over a finite commutative quasi-Frobenius ring in the work of Shiromoto [5]. We show that there exists a…
