The problem of universal fault-tolerant quantum computation for a class of decoherence-free subspaces (DFS) was addressed. A model of correlated errors forming an Abelian subgroup of the Pauli group was studied. The errors in this model were the elements of the stabilizer and were correlated. No spatial symmetry in the system-bath interaction was implied and this enlarged the scope of the theory.
