Quantum systems can be simulated by classical computers, but the growth of the problem is exponential. If you can leverage actual quantum systems to do the work, then you can take a shortcut, for certain classes of problems.
> In a way, it is like answering questions about airplane design by studying a model airplane in a wind tunnel – solving problems with a physical simulation rather than a digital computer.
- tormeh 12y agoThe same principle applies to analogue computer chips. They're probably still faster for some tasks than digital ones, but more expensive and fragile.
