Large-Scale Spatial Photonic Ising Machines (Invited)
Facing the challenge of efficiently and accurately solving large-scale combinatorial optimization problems, spatial photonic Ising machines, by leveraging capabilities of space-division multiplexing for large-scale implementation, an intuitive and straightforward fully-connected Ising mapping mechanism, and programmable combinatorial optimization approaches, have emerged as a significant technological path for the deployment and validation of Ising machines, receiving widespread attention from both academia and industry. This paper introduces the photonic Ising mapping principle of spatial photonic Ising machines, the main technical challenges, and future research prospects. It especially focuses on three key technical issues: flexible spatial photonic Ising mapping methods, general-purpose spatial photonic Ising machine architecture, and noise-enhanced photonic Ising optimization methods.
