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…
Digital-twin imaging based on descattering Gaussian splatting
Suguru Shimomura, Kazuki Yamanouchi, Jun Tanida
Three-dimensional imaging through scattering media is important in medical science and astronomy. We propose a digital-twin imaging method based on Gaussian splatting to observe an…
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…
