Ising machine
An Ising machine is a special-purpose computer that solves combinatorial optimization problems by mapping them onto the search for the ground state of an Ising model and letting a physical system, rather than an algorithm, find that ground state. The "spins" of the model are represented by bistable states of oscillators, light pulses, superconducting circuits or electronic devices, and the interactions between spins by programmable couplings. Ising machines have been an active field of research since the 2010s as an alternative to conventional computers for hard optimization tasks.
