Propagation Rules of Subsystem Codes

Abstract

We demonstrate propagation rules of subsystem code constructions by extending, shortening and combining given subsystem codes. Given an $[[n,k,r,d]{]}_q$ subsystem code, we drive new subsystem codes with parameters $[[n+1,k,r,\ge d]{]}_q$, $[[n-1,k+1,r,\ge d-1]{]}_q$, $[[n,k-1,r+1,d]{]}_q$. The interested readers shall consult our companion papers for upper and lower bounds on subsystem codes parameters, and introduction, trading dimensions, families, and references on subsystem codes [1][2][3] and references therein.
