Stochastic quantization serves to quantize [[Euclidean field theory|Euclidean field theories]],<ref name=damgaard>{{cite journal|last=Damgaard |first=Poul|author2=Helmuth Huffel |title=Stochastic Quantization |journal=Physics Reports|year=1987|volume=152|issue=5&6|pages=227–398|url=http://homepage.univie.ac.at/helmuth.hueffel/PhysRep.pdf|access-date=8 March 2013|bibcode = 1987PhR...152..227D |doi = 10.1016/0370-1573(87)90144-X |hdl=1721.1/3101|hdl-access=free}}</ref> and is used for numerical applications, such as [[numerical simulation]]s of [[Gauge theory|gauge theories]] with [[fermion]]s. This serves to address the problem of [[fermion doubling]] that usually occurs in these numerical calculations.
