New Quantum Codes from CSS Codes

Abstract

We present a new propagation rule for CSS codes. Starting with a CSS code $[[n,k,d]{]}_q$, we construct a CSS code with parameters $[[n-2,k,d-1]{]}_q$. In general, one would only obtain a code with parameters $[[n-2,k,d-2]{]}_q$. The construction applies to asymmetric quantum codes from the CSS construction as well.
