Marginal photon number distributions for photon-subtracted TMSVS with l. a l = 0, b l = 1, c l = 2, and d l = 3. The overall system’s efficiency is ~16.25% and the best-fit squeezing parameter is obtained to be 0.66. The red-dashed and black-dotted curves represent Poissonian and thermal photon distributions, respectively. These curves are obtained from a fit to the experimental data with mean photon numbers equal to a 〈n〉 = 0.7, b 〈n〉 = 0.9, c 〈n〉 = 1.68, and d 〈n〉 = 2.05. The coefficients of determination (R2) for the fittings are shown in each panel
