    "abstract": "We show how macroscopically distinct quantum superposition states\n(Schroedinger cat states) may be used as logical qubit encodings for the\ncorrection of spontaneous emission errors. Spontaneous emission causes a bit\nflip error which is easily corrected by a standard error correction circuit.\nThe method works arbitrarily well as the distance between the amplitudes of the\nsuperposed coherent states increases.",
