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.
