    "abstract": "We present relaxed criteria for quantum error correction which are useful\nwhen the specific dominant noise process is known. These criteria have no\nclassical analogue. As an example, we provide a four-bit code which corrects\nfor a single amplitude damping error. This code violates the usual Hamming\nbound calculated for a Pauli description of the error process, and does not fit\ninto the GF(4) classification.",
