    "abstract": "A method for measuring an integral of a classical field via local interaction\nof a single quantum particle in a superposition of 2^N states is presented. The\nmethod is as efficient as a quantum method with N qubits passing through the\nfield one at a time and it is exponentially better than any known classical\nmethod that uses N bits passing through the field one at a time. A related\nmethod for searching a string with a quantum particle is proposed.",
