Abstract
We study the apparent nonlocality of quantum mechanics as a transport problem. If space is a physical entity through which quantum information (QI) must be transported, then one can define its speed. If not, QI exists apart from space, making space in some sense `nonphysical'. But we can still assign a `speed' of QI to such models based on their properties. In both cases, classical information must still travel at $c$, though in the latter case the origin of local spacetime itself is a puzzle. We consider the properties of different regimes for this speed of QI, and relevant quantum interpretations. For example, we show that the Many Worlds Interpretation (MWI) is nonlocal because it is what we call `spatially complete'.
