WebMar 24, 2002 · The Many-Worlds Interpretation (MWI) of quantum mechanics holds that there are many worlds which exist in parallel at the same space and time as our own. The existence of the other worlds makes it possible to remove randomness and action at a distance from quantum theory and thus from all physics. WebFor many years, the fields of quantum mechanics and computer science formed distinct academic communities.
