Most people don't know about the existence of quantum computers. Almost no one understands how they work, but theories include bizarre-sounding explanations like, "they reach into alternate universes to derive the correct answers to highly complex computational problems."
Quantum computers are not made of simple transistors and logic gates like the CPU on your PC. They don't even function in ways that seem rational to a typical computing engineer. Almost magically, quantum computers take logarithmic problems and transform them into "flat" computations whose answers seem to appear from an alternate dimension.
For example, a mathematical problem that might have 2 to the power of n possible solutions -- where n is a large number like 1024 -- might take a traditional computer longer than the age of the universe to solve. A quantum computer, on the other hand, might solve the same problem in mere minutes because it quite literally operates across multiple dimensions simultaneously.
