What I don't understand is why a computer programmed to assume a superposition, say of two states, represents a system in both states simultaneously (which I find to be false for reasons previously stated), would speed up any calculation. Can anyone answer this question? AG > > > John K Clark > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
