From home PCs to business servers, computers are a central part of our everyday life, and their power continues to grow at an astounding rate. However, there are two big problems looming on the horizon for classical computers. The first is a fundamental limit on how many transistors we can pack into a single processor. Eventually, a totally new approach will be needed if we are to continue to increase their processing capacity. The second is that even the most powerful computers struggle with certain important problems, such as the cryptographic algorithms that keep your credit card number safe on the internet, or the optimization of routes for delivering packages.

The solution to both problems may be quantum computers, which take advantage of the rules of physics that govern very small length scales, as with atoms and electrons. In the quantum regime, electrons act more like waves than billiard balls, with positions that are "smeared-out" rather than definite. In addition, various components can become entangled, such that the properties of each one cannot be completely described without reference to...
