    "abstract": "We develop a structure theory for decoherence-free subspaces and noiseless\nsubsystems that applies to arbitrary (not necessarily unital) quantum\noperations. The theory can be alternatively phrased in terms of the\nsuperoperator perspective, or the algebraic noise commutant formalism. As an\napplication, we propose a method for finding all such subspaces and subsystems\nfor arbitrary quantum operations. We suggest that this work brings the\nfundamental passive technique for error correction in quantum computing an\nimportant step closer to practical realization.",
