Also a layperson, but as I understand it. We do have the algorithms to simulate quantum systems with n states to arbitrary precision through brute force. But they require that you can put ~n bits into a superposition state. If your computer doesn't have that capability, you can simulate it to arbitrary precision with ~2^n bits.
