Figure 3

Work distribution for a quantum annealer. Distribution \({\mathscr{P}}({\rm{\Delta }}\omega )\) – (3) for the quantum Ising chain (6) implemented on a D-Wave 2X chip. Plots (a,b) show the final results for J = −1 (antiferromagnetic) and J = 1 (ferromagnetic) cases, respectively. To obtain each distribution \({\mathscr{P}}({\rm{\Delta }}\omega )\) the experiment was repeated \(N={10}^{6}\). Error bars are negligible and thus not shown in the plots. The renormalized energy is given by \({\omega }_{L}=\omega /(L-1)\), where L is the length of a randomly chosen chain.
