Fig. 5: Distortion of single (qu)bit memory models.
From: Implementing quantum dimensionality reduction for non-Markovian stochastic simulation
a KL divergence dKL of experimentally-obtained statistics from our quantum models (orange) from exact statistics, and lower bound on the divergence of single bit distorted classical models (yellow) for N = [3. . 8], Γ = 0.5, and V = 0.4. b–d Analogous plots for N = 3 (b), N = 4 (c), and N = 5 (d) with varying Γ. Distortions of quantum models are shown as discs and lower bounds on the distortion of single-bit classical models as solid lines. Error bars are omitted as they are smaller than data points.
