Right. So, to be clear, the first line of the first quote is correct,
but the second is *not*. An MRI makes dramatic changes on the quantum
level, but absolutely *no* detectable change in the personality,
memory, etc., of the individual. Thus, the spin state of the hydrogen
atoms in your brain is absolutely irrelevant to the health and welfare
of your mind, and thus, need not be duplicated by a teleportation
device.
