    "abstract": "We propose a realizable experimental scheme to prepare superposition of the\nvacuum and one-photon states by truncating an input coherent state. The scheme\nis based on the quantum scissors device proposed by Pegg, Phillips, and Barnett\n[Phys. Rev. Lett. 81, 1604 (1998)] and uses photon-counting detectors, a\nsingle-photon source, and linear optical elements. Realistic features of the\nphoton counting and single-photon generation are taken into account and\npossible error sources are discussed together with their effect on the fidelity\nand efficiency of the truncation process. Wigner function and phase\ndistribution of the generated states are given and discussed for the evaluation\nof the proposed scheme.",
