报告摘要：

      We survey some results in Boson sampling and its applications. As an application, we consider scattershot boson sampling using states with squeezed vacuum states coupled to a linear optical network. We show that we can efficiently approximate the molecular vibronic spectra in polynomial time to obtain the minimum value of the target accuracy and the theoretical upper limit of accuracy. We also fabricated a large-scale integrated quantum photonic chip with 16 modes of single-mode squeezed vacuum states and a fully programmable 16-mode interferometer as a versatile simulation platform. Molecular vibronic spectra of formic acid and thymine were accurately simulated using the integrated chip with high reconstructed fidelity.
