Waveguides make quantum computers more reliable

Quantum computing is one of the current big things in both physics and computer science circles. But there is a serious divide between what we think might be possible and what we can, in fact, do. There are theorists out there working themselves into a frenzy, trying to show that quantum computing will make a smoother latte. On the experimental side, many researchers are still in various stages of single gate operations. It is like the difference between trying to make a valve and knowing what you can do with lots of valves once you have them.
