I will discuss quantum Monte Carlo methods based on the stochastic series expansion approach at finite temperature and related ground state projector methods. Examples will be given to show how these methods can deliver reliable results for some of the most challenging problems in quantum magnetism, with a focus on systems with dimer ordering and the related deconfined quantum criticality scenario. I will also explain finite-size scaling of numerical data and how to connect results to the renormalization group approach.
