A silicon chip fabricated in a standard semiconductor foundry demonstrates that coupled ring oscillators can solve optimization problems targeted by quantum computers, and are quicker, cheaper and more energy-efficient than digital solvers. The 1,968 oscillator integrated circuit consumes 0.042 W and finds a solution within 50 oscillation cycles.
