    Measurement-induced nonlinear operation in linear optics is a promising technique to realize quantum computation and communications. Such an operation has been demonstrated via the generation of photon-subtracted squeezed states, namely, Schrödinger-cat states. Nielsen and Mølmer have proposed an efficient scheme to generate the cat states with larger amplitudes relative to previous experimental results. We present a simple experimental implementation of their scheme and analyze it while considering experimental imperfections. Our study indicates that the current photon detection technology meets the conditions necessary for their operation.
