Extended Data Fig. 3: Bar chart depiction of response matrices.
From: Optomechanical realization of the bosonic Kitaev chain
(a) Bar chart representation of the susceptibility matrices \({(\gamma {\chi }_{jk})}^{2}/4\) plotted in Fig. 1d, for G = 0.75, G = 1.0, and G = 1.25. (b) The same data as in (a), depicted in a basis of rotated quadratures chosen to numerically minimize the weight of the off-diagonal blocks. The close correspondence between (a) and (b) illustrates that the original (unrotated) calibration of quadratures was performed accurately, and represents the quadrature sensitivity of the response optimally.
