Figure 7. Simulated quantum state tomography of a noisy squeezed state.

Tomography reconstruction of a two-mode squeezed state affected by phase noise and a systematic shift in the variance of the quadrature sum, as in the experiment. Here we have used the experimental parameters: p≈100 measurements, n_θ=29 phase values and a bin size of dx=0.25. The reconstructed state agrees very well with Fig. 4 of our manuscript, both qualitatively (showing both the presence of off-diagonal terms and asymmetry) and quantitatively (with a quantum a fidelity of about 90%).
