However, this is slightly irritating:
“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.”
In the spirit of a very popular television program:
Let me explain for any readers who are slightly confused at this point: Quantum computers will be very good at solving certain types of hard problems somewhat faster than classical computers. This should become some sort of mantra. (If anyone can think of a catchy version that would be cool).
They won’t be general purpose machines. The best way to think of a QC is more like a co-processor (say like a hardware graphics accelerator).
The types of problems that they will be good at solving are exciting and interesting in themselves. Quantum computers are cool enough without the overhype 🙂
