We are totally ready for a quantum computer. Browse the dusty Engadget archives
and you'll find many posts about the things, each charting another step along the way to our supposed quantum future. Here's another step, one that we think is a pretty big one. An international team of scientists has managed to generate 10 billion quantum entangled bits, the basic building block of a quantum computer, and embed them all in silicon which is, of course, the basic building block of a boring computer. It sounds like there's still some work to be done to enable the team to actually modify and read the states of those qubits, and probably a decade's worth of thumb-twiddling before they let any of us try to run Crysis
on it, but yet another step has been made.
