Fig. 3: Results of the ground state search for the 20-dimensional Möbius-Ladder model.

a An experimentally measured Hamiltonian evolution curve in a single run. The inset shows the Ising model to be solved. Two arrows denote the position of the initial state in (b) and the final accepted state in (c), respectively. b The beam power of the detected image corresponding to a randomly generated initial state with a high Hamiltonian. The left inset denotes the positions of 20 beams. The color bar denotes the incident power on each pixel. c The beam power of the detected image corresponding to a final accepted state with a low Hamiltonian. The left inset denotes the positions of 20 beams. The color bar denotes the incident power on each pixel.
