    "abstract": "We present a scheme to conditionally generate an arbitrary superposition of a\npair of coherent states from a squeezed vacuum by means of the modified photon\nsubtraction where a coherent state ancilla and two on/off type detectors are\nused. We show that, even including realistic imperfections of the detectors,\nour scheme can generate a target state with a high fidelity. The amplitude of\nthe generated states can be amplified by conditional homodyne detections.",
