At 1000 qubits, the new processor considers 2^1000 possibilities simultaneously, a search space which dwarfs the 2^512 possibilities available to the 512-qubit D-Wave Two.</i><p>Since we still aren't able to factor any large numbers with it, those 2^1000 bits don't really work like they say they do. I'm guessing there are many caveats behind their description.<p>I would appreciate any explanation from an expert.
