A coherent Ising machine (CIM) has been studied as a physical computer solving optimization problems based on the Ising model, and the Potts model is known as an extended version of the Ising model. In this paper, we propose a fiber loop with a multiple-phase sensitive amplifier, which outputs discrete phase values more than two as a basic physical system to solve the Potts model in the same way as CIM, whose oscillation characteristics are simulated with our traveling-wave model.
