New quantum codes constructed from some self-dual additive $\mathbb{F}_4$-codes (1805.12229v1)
Published 30 May 2018 in math.CO, cs.IT, and math.IT
Abstract: For $(n,d)= (66,17),(78,19)$ and $(94,21)$, we construct quantum $[[n,0,d]]$ codes which improve the previously known lower bounds on the largest minimum weights among quantum codes with these parameters. These codes are constructed from self-dual additive $\mathbb{F}_4$-codes based on pairs of circulant matrices.
