    "abstract": "We have studied how decoherence affects a quantum walk on the line. As\nexpected, it is highly sensitive, consisting as it does of an extremely\ndelocalized particle. We obtain an expression for the rate at which the\nstandard deviation falls from the quantum value as decoherence increases and\nshow that it is proportional to the number of decoherence \"events\" occuring\nduring the walk.",
