Precision Hamiltonian Encoding in Full-Aperture Spatial Photonic Ising Machines
D. Karanikolopoulos, P. S. Karavelas, L. Mouchliadis +11
Spatial photonic Ising machines (SPIMs) offer compact, room-temperature hardware with inherently parallel, energy-efficient, single-shot optical evaluation of the Ising Hamiltonian…
Phase Retrieval via Gain-Based Photonic XY-Hamiltonian Optimization
Richard Zhipeng Wang, Guangyao Li, Silvia Gentilini +3
Phase-retrieval from coded diffraction patterns (CDP) is important to X-ray crystallography, diffraction tomography and astronomical imaging, yet remains a hard, non-convex inverse…
Ising machine by dimensional collapse of nonlinear polarization oscillators
Salvatore Chiavazzo, Marcello Calvanese Strinati, Claudio Conti +1
Ising machines show promise as ultrafast hardware for optimizations encoded in Ising Hamiltonians but fall short in terms of success rate and performance scaling. Here, we propose…
Fully Programmable Spatial Photonic Ising Machine by Focal Plane Division
Daniele Veraldi, Davide Pierangeli, Silvia Gentilini +10
Ising machines are an emerging class of hardware that promises ultrafast and energy-efficient solutions to NP-hard combinatorial optimization problems. Spatial photonic Ising machi…
