Have you heard of the particle wave theory? In practical terms, it means that bizarre and counterintuitive effects occur on very small scales, and they can be harnessed.
This “quantum superposition” effect will, for example, utterly transform how we do “computer math.” Currently, nearly everything done by computers is done in binary. The smallest piece of information a computer handles, the bit, is either one or zero, something or nothing. A quantum computer, though, would be able to store and work with number systems other than binary.
This means computers would become exponentially more powerful because each “quantum bit” (qubit) could store a much greater range of numbers than the two that binary math restricts us to. Imagine a laptop with the computing power of the world’s 10 most powerful supercomputers. Then you begin to grasp the potential of quantum computing.
