    "abstract": "Error correction, in the standard meaning of the term, implies the ability to\ncorrect all small analog errors and some large errors. Examining assumptions at\nthe basis of the recently proposed quantum error-correcting codes, it is\npointed out that these codes can correct only a subset of errors, and are\nunable to correct small phase errors which can have disastrous consequences for\na quantum computation. This shortcoming will restrict their usefulness in real\napplications.",
