Abstract
This paper discusses different ways of expressing quantum properties as stochastic averages. It is explained how such a formal mathematical connection between quantum mechanics and stochastic processes may be used to compute quantum observables (Monte Carlo simulation). The problems in applying stochastic methods to fermion systems are discussed and a few illustrative results for atoms and molecules are presented.
