Quantum difference engine

If this doesn't get a link from Glen, there is no justice. This month's Scientific American is reporting that some nanotech physics types thinks nano-wires may be used to construct switches for use in quantum computers. This would actually be a mechanical quantum computer. The non-technical explanation is that the wires are so small that when you twist them, they, uh, do some quantum mechanical thing that, um, acts like a quantum switch. Whether it works or not, it certainly has applications to science fiction.
