      abstract     = {We give an introduction to the calculation of path
                      integrals on a lattice, with the quantum harmonic oscillator
                      as an example. In addition to providing an explicit
                      computational setup and corresponding pseudocode, we pay
                      particular attention to the existence of autocorrelations
                      and the calculation of reliable errors. The over-relaxation
                      technique is presented as a way to counter strong
                      autocorrelations. The simulation methods can be extended to
                      compute observables for path integrals in other settings.},
