Abstract
This paper proposes a novel approach to implement an antiferromagnetic model using optoelectronic correlation computing with a spatial photonic Ising machine (SPIM). The authors leverage a gauge transformation to encode spins and interaction strengths within a single phase-only spatial light modulator (SLM), simplifying the experimental setup. Experimental results demonstrate accelerated ground-state search for a number-partitioning problem involving 40,000 spins, showcasing the method's scalability and programmability for various applications in statistical physics and combinatorial optimization.
