A Monte Carlo method is introduced that overcomes the problem of alternating signs in Handscomb's method of simulating antiferromagnetic quantum Heisenberg systems. The scheme is applied to both bipartite and frustrated lattices. Results of internal energy, specific heat, and uniform and staggered susceptibilities are presented suggesting that quantum antiferromagnets may now be studied as extensively as classical spin systems using conventional Monte Carlo techniques.
