The experimental results of the 1D Ising machine. a Spin evolution as a function of the number of roundtrips. The zoomed-in view on the left shows the details of the spin evolution from the noise state to a relatively stable domain. The zoomed-in view on the right shows the evaporation of the short domain. b The Ising energy and the mean amplitude of the spins as functions of the number of roundtrips. c The histograms of the domain length at different small-signal gains. At the small gain, the domain is relatively long, while the frequency of the shot domain increases at a large gain. d The defect density and correlation length as functions of the small-signal gain
