Encoding Arbitrary Ising Hamiltonians on Spatial Photonic Ising Machines
Physical Review LettersPhotonic Ising Machines constitute an emergent new paradigm of computation, geared towardstackling combinatorial optimization problems that can be reduced to the problem of finding theground state of an Ising model. Spatial Photonic Ising Machines have proven to be advantageousfor simulating fully connected large-scale spin systems.

Annealing by simulating the coherent Ising machine
Optics Express, 2019 The coherent Ising machine (CIM) enables efficient sampling of low-lying energy states of the Ising Hamiltonian with all-to-all connectivity by encoding the spins in the amplitudes of pulsed modes in an optical parametric oscillator (OPO). The interaction between the pulses is realized by means of measurement-based optoelectronic feedforward which ...

Probabilistic Computing via Gate‐Tunable Random Telegraph Noise
Advanced Science, EarlyView.Intrinsic random telegraph noise in metal–oxide–semiconductor field‐effect transistors is harnessed to create gate‐tunable probabilistic bits. By modulating carrier‐trapping dynamics, the device produces stochastic binary outputs with a continuous bias‐to‐probability transfer.
