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…
