{{Use American English|date=January 2019}}{{Short desc|Computational simulation method for open quantum systems}}The '''quantum jump method''', also known as the '''[[Monte Carlo method|Monte Carlo]] wave function (MCWF) method''', is a technique in [[computational physics]] used for simulating [[open quantum system]]s. The quantum jump method was developed by [[Jean Dalibard|Dalibard]], Castin and Mølmer, with a very similar method also developed by Carmichael in the same time frame. Other contemporaneous works on wave-function-based [[Monte Carlo method|Monte Carlo]] approaches to open quantum systems include those of Dum, [[Peter Zoller|Zoller]] and [[Helmut Ritsch|Ritsch]] and Hegerfeldt and Wilser.<ref name="MCD1993" /><ref name="PrimaryPapers">The associated primary sources are, respectively:
