From: Experimental quantum simulation of non-Hermitian dynamical topological states using stochastic Schrödinger equation

Fig. 8

kx = −1.286, ky = −0.257. a–d shows results from 50, 100, 200, and 5,000 noise configurations, respectively. e shows results from 5, 50, 500 noise configurations, respectively. Each panel contains four average results from the same number of configurations. f Each 〈σ(k, t)〉 of four pre-simulated noise configurations (left panel). 〈〈〈σ(k, t)〉〉〉noise averaged by these four pre-simulated noise configurations (right panel). g Experimental and theoretical results of four configurations of noise obtained by pre-simulation. The left four small panels show the experimental and theoretical results of each noise configuration. The line represents the simulation value, and the dot represents the experimental results. The right panel shows the average results from these four noise configurations.
