Left, schematic illustration of eigenmodes of the adjacency matrix A and the corresponding squeezing ellipses, with orientations specified by eigenvalues λ_m = cot φ_m. Right, measured variances ζ^2 in the four eigenmodes, showing squeezing at the specified spinor phases φ_m (black dashed lines). Error bars show 1 s.d. confidence interval.
