Abstract

The quantum scissors drive (QSD) proposed by Pegg et al. was analyzed in detail using realistic descriptions for the detectors and single-photon source. It was shown that the scheme is realizable with high fidelity using commercially available detectors and spontaneous parametric down-conversion (SPDC) as the single-photon source. With a further analysis using quasidistributions, it was clarified that the states prepared with the QSD scheme have nonclassical properties. Furthermore, the value of the preferred relative phase between the vacuum and single-photon states of the input coherent light was preserved at the truncated output state.
