A brief overview of the diffusion quantum Monte Carlo method is given. We illustrate the application to ground-state calculations by a study of the relative stability of carbon clusters near the crossover to fullerene stability, thereby determining the smallest stable fullerene. The application to excited states is illustrated via a study of excitonic states in small hydrogenated silicon clusters.
