a Coherence window, cycle-and-chain-averaged clustering, \({{{{{{{\mathcal{C}}}}}}}}\), as a function of system size, L. b Coherence window, cycle-and-chain-averaged path length, ℓ, as a function of system size, L. c Normalized node strength distribution, P[gi/(L − 1)], amalgamated over all system sizes. d–g Heatmap and force-directed41 complex network visualization of mutual information network for L = 23 at t = 9 (blue: emulated; red: raw data from Weber; green: post-selected; black: post-selected incoherent uniform randomness). Where present, error bars represent one standard deviation from the mean averaged over four different chains and cycles within the coherence window.
