Quantum Monte Carlo (QMC) simulations constitute nowadays one of the mostpowerful methods to study strongly correlated quantum systems, provided that no"sign problem" arises. However, many systems of interest, including highlyfrustrated magnets, suffer from an average sign that is close to zero instandard QMC simulations. Nevertheless, a possible sign problem depends on thesimulation basis, and here we demonstrate how a suitable choice of clusterbasis can be used to eliminate or at least reduce the sign problem in highlyfrustrated magnets that were so far inaccessible to efficient QMC simulations.We focus in particular on the application of a two-spin (dimer)-based QMCmethod to the thermodynamics of the spin-1/2 Shastry-Sutherland model forSrCu$_2$(BO$_3$)$_2$.
