Abstract
Spin Glasses (SG) are paradigmatic models for physical, computer science, biological and social systems. The problem of studying the dynamics for SG models is NP-hard, i.e., no algorithm solves it in polynomial time. Here we implement the optical simulation of an SG, exploiting the N segments of a Digital Micromirror Device to play the role of the spin variables, combining the interference at downstream of a scattering material to implement the random couplings and measuring the transmitted light intensity to retrieve the system energy. We demonstrate that This optical platform beats digital computation for large-scale simulation (N>12000).
