  • Recovering missing phase from measured intensity is central to X-ray crystallography and diffraction imaging but is a hard, non-convex inverse problem. The authors reformulate coded diffraction pattern phase retrieval exactly as minimizing a continuous XY energy and solve it with gain-based photonic oscillator networks with efficient scaling and noise tolerance.

  • Spin simulators can solve many combinatorial optimization problems that can be represented by spin models, but they are limited to low-dimensional spins. Here the authors propose a simulator of multidimensional spins in arbitrary dimension, using a system of coupled parametric oscillators with a common pump.

  • Spatial photonic Ising machine (SPIM) has shown promise as a power efficient Ising machine, but is currently limited in the range of problems that it can implement. The authors identify factors influencing the performance of SPIM and investigate methods to expand the range of problems available to SPIM.
