• Abstract: We show the formation of Schrodinger cat-like states (SCLSs) during the spontaneous parametric down-conversion (SPDC) process when the pump mode is considered quantum and depleted. For the first time, we show the formation of SCLSs in the fundamental and second harmonic modes under non-dissipative and dissipative regimes. The Wigner function is used to visualize qualitatively SCLSs. We have performed quantitative analysis of SCLSs by calculating values of the mean number of photon, photon number distribution, the variance of quadrature component, the Fano factor and fidelity.

  The Schr"odinger cat (SC) states are important in quantum optics because of their non-Gaussian properties. We propose a novel method of conditional generation of bright (multi-photon) SC states that uses degenerate parametric down-conversion and heralding measurement of the photon number in the pump mode.
