Deterministic Ground-State Search in a Spatial Photonic Ising Machine by Phase Retrieval
Suguru Shimomura, Jun Tanida, Yusuke Ogura
A spatial photonic Ising machine (SPIM) solves large-scale combinatorial optimization problems by computing the Ising Hamiltonian through an optical Fourier transform. However, the…
Parallel spatial photonic Ising machine using spatial multiplexing for accelerating combinatorial optimization
Suguru Shimomura, Jun Tanida, Yusuke Ogura
A spatial photonic Ising machine (SPIM) handles large-scale combinatorial optimization problems owing to optical processing with spatial parallelism. However, iterative feedback in…
Spatial-photonic Ising machine by space-division multiplexing with physically tunable coefficients of a multi-component model
Takumi Sakabe, Suguru Shimomura, Yusuke Ogura +4
This paper proposes a space-division multiplexed spatial-photonic Ising machine (SDM-SPIM) that physically calculates the weighted sum of the Ising Hamiltonians for individual comp…
