Quantum computing uses the spins on atoms as high/low, and many states in between including both 0 and 1 at the same time. Data like this is extremely volatile, along with the fact that there aren't many uses for it yet. Although as traditional computing standards use voltage running through wires, as those wires become smaller(Intel is using 22nm lithography and are planning to release new CPUs in 2014 Q2/3 with 14nm lithography, to put AMD in this, they're still at 32nm), the problem occurs when trying to send electrons through wires that are to small for them to fit it. This is where quantum computers true potential is unraveled. There are no "traditional" transistors. It's actually based on the spinning of atoms. The D-Wave is one of the few personal quantum computers.
