Extended Data Fig. 1: Characteristics of the squeezed state Vp from the decomposition for single-mode cases.
From: Classical algorithm for simulating experimental Gaussian boson sampling
(a) Relation between the actual squeezing parameter s and the input squeezing r for different transmission rate η. (b) Ratio of the actual squeezed photons to the total photons of the output state V. (c) and (d) Actual squeezing parameter and squeezed photon numbers when the input squeezing parameter is infinite. The dots represent the Borealis, Jiuzhang2.0, and Jiuzhang3.0’s circuit’s transmission rate and their largest actual squeezing and squeezed photons, assuming that infinite input squeezing is used.
