Re: Emulation
Quantum computer emulators exist, but you don't get the efficiency.
It's a bit like having to emulate multiplication by adding number a+a+a+a+....+a. You get the right answer, but it's **slow**
Quantum computers use superposition, which is a little like white-light being made up of different colours all doing their own thing, so the level of parallelism is going to be another slow thing to emulate.
If you think about it, classical computers are basically just NAND gates glued together, it's not surprising that they fundamentally can't do everything...
