Conditional generation of an arbitrary superposition of coherent states
arXiv:quant-ph/0702126 · doi:10.1103/PhysRevA.75.064302
Abstract
We present a scheme to conditionally generate an arbitrary superposition of a pair of coherent states from a squeezed vacuum by means of the modified photon subtraction where a coherent state ancilla and two on/off type detectors are used. We show that, even including realistic imperfections of the detectors, our scheme can generate a target state with a high fidelity. The amplitude of the generated states can be amplified by conditional homodyne detections.
