RESUMO

We discuss how reweighting and histogram methods for classical systems can be generalized to quantum models for discrete and continuous time world line simulations, and the stochastic series expansion (SSE) method. Our approach allows to apply all classical reweighting and histogram techniques for classical systems, as well as multicanonical or Wang-Landau sampling to the quantum case.
