\def\ket#1{{ \left| #1 \right> }} \def\bracket#1{{ \left( #1 \right) }} \def\bra#1{{ \left< #1 \right| }} \left[7,1 \right] Steane code is an ubiquitous example of Calderbank-Shor-Steane (CSS) class of quantum error correction codes. Steane code was constructed from classical \left[7,4,3 \right] Hamming code whose parity-check matrix takes the following form \begin{equation..
