WebbHowever, the full Hilbert space has $2^{n}$ states, which means a general (non-product) state requires specification by $2^n$ different complex numbers. Obviously there are infinite numbers of each since the amplitudes are continuous, but I think it should be clear that the latter case admits many more states, especially if you discretize the space.
