We study non-Gaussian states generated by two-photon subtraction from a continuous-wave (cw) squeezed light source. In a cw scheme, one can subtract two photons from the source with a designated time separation and can generate temporally multiplexed superposition states of continuous variables. We numerically study the properties of these states in light of bosonic interference in the time domain. In an appropriate temporal mode, an amplified superposition state of continuous variable is produced in a region where the time separation is comparable with the coherence time of squeezed packets.
