exponential loss of precision in quantum Monte Carlo when sampling weights for fermions turn negative, shown to be computationally hard in general.

In quantum physics, fermion sign problem refers to exponential loss of precision in quantum Monte Carlo when sampling weights for fermions turn negative, shown to be computationally hard in general. This meaning comes from Troyer (2005) in Physical Review Letters.[1]
