    "abstract": "Since there are many examples in which no decoherence-free subsystems exist\n(among them all cases where the error generators act irreducibly on the system\nHilbert space), it is of interest to search for novel mechanisms which suppress\ndecoherence in these more general cases. Drawing on recent work\n(quant-ph/0502153) we present three results which indicate decoherence\nsuppression without the need for noiseless subsystems. There is a certain\ntrade-off; our results do not necessarily apply to an arbitrary initial density\nmatrix, or for completely generic noise parameters. On the other hand, our\ncomputational methods are novel and the result--suppression of decoherence in\nthe error-algebra approach without noiseless subsystems--is an interesting new\ndirection.",
