Non-Gaussian spectral estimation: noise bispectrum. a Experimental data (blue triangles), Monte Carlo simulations (orange squares), and ideal values (gray circles) for the bispectrum of the engineered dephasing noise. The error bars indicate that the experimental bispectrum agrees with both the ideal bispectrum and Monte Carlo simulations of the protocol within 95% confidence intervals. b Estimated non-Gaussian phase angles φ. Error bars represent 95% confidence intervals. c 3D visualization of the ideal bispectrum. d 3D visualization of the reconstructed bispectrum for the experimental data
