A general theory of quantum error avoiding codes is established, and new light is shed on the relation between quantum error avoiding and correcting codes. Quantum error avoiding codes are found to be a special type of completely degenerate quantum error correcting codes.

A permutationally invariant n-bit code for quantum error correction can be realized as a subspace stabilized by the non-Abelian group S n . The code is spanned by bases for the trivial representation, and all other irreducible representations, both those of higher dimension and orthogonal bases for
