IDG Connect How close is quantum computing?

"That sounds like sci-fi…!" is a term that gets bandied around a lot. Yet in the case of quantum computing, the really weird thing is just how recent the whole idea is. In fact, the concept wasn't invented until the early 1980s by Nobel-prize winning physicist Richard Feynman in a paper entitled "Simulating physics with computers". And sci-fi didn't get its teeth into it until the early 1990s – although, Multivac the supercomputer in Isaac Asimov's 1956 short story "The Last Question" from 1956, does show some parallels. These days everyone is getting on the bandwagon.
