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…
Equalized Hyperspin Machine
Marcello Calvanese Strinati, Claudio Conti
The reliable simulation of spin models is of critical importance to tackle complex optimization problems that are intractable on conventional computing machines. The recently intro…
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…
Roadmap on Neuromorphic Photonics
Daniel Brunner, Bhavin J. Shastri, Mohammed A. Al Qadasi +147
This roadmap consolidates recent advances while exploring emerging applications, reflecting the remarkable diversity of hardware platforms, neuromorphic concepts, and implementatio…
Emergent Equilibrium in All-Optical Single Quantum-Trajectory Ising Machines
Jacopo Tosca, Marcello Calvanese Strinati, Claudio Conti +1
We investigate the dynamics of multi-mode optical systems driven by two-photon processes and subject to non-local losses, incorporating quantum noise at the Gaussian level. Our fin…
