By the strange laws of quantum mechanics, Folger, a senior editor at Discover, notes, an electron, proton, or other subatomic particle is "in more than one place at a time," because individual particles behave like waves, these different places are different states that an atom can exist in simultaneously. Ten years ago, Folger writes, David Deutsch, a physicist at Oxford University, argued that it may be possible to build an extremely
powerful computer based on this peculiar reality. In 1994, Peter Shor, a mathematician at AT&T Bell Laboratories in New Jersey, proved that, in theory at least, a full-blown quantum computer could factor even the largest numbers in seconds--an accomplishment impossible for even the fastest conventional computer.
An outbreak of theories and discussions of the possibility
of buildig a quantum computer now permeates itself thoughtout the quantum fields of technology and research. It's roots can be traced back to 1981, when Richard Feynman......
