Networks of coupled parametric resonators (parametrons) hold promise for parallel computing architectures. These are classical systems with period-doubling bifurcations, where the logic information is stored in oscillation modes of the system. Such networks similarly realize the physics of so-called discrete time crystals (DTCs). The latter are a many-body state of matter whose dynamics are slower than the forces acting on it. I will report on our theoretical and experimental work on parametron networks, their relation to DTCs and their potential application for the realization of coherent Ising machines.
