(a) Shows the photon number evolution for the four initial states (Eqs. 2–5) across the waveguides, from the initial to the final position of the DW as depicted in Fig. 1c. (b) Shows the single-mode quadrature magnitude evolution of the single-mode squeezed state when moving the DW. (c) Shows the two-mode squeezed quadrature magnitude evolution between the edge and the moving DW.
