jseal - I agree that the engineering needed for teleportation is overwhelming. I don't think Dr. Heisenberg would stand in the way of this process.

The uncertainty principle can be stated as

uncertainty in position (X) multiplied by the uncertainty in velocity (V) > h/m

Where h is Planck’s constant and m is the mass of the particle.

In the quantum world, each measurement changes the system. To measure the position of the object will introduce an uncertainty in the velocity, and vice versa. This is what it means to have the number on the right side of the equation not equal to zero. As the uncertainty in one variable (V) approaches zero, the uncertainty in the other (X) must increase to keep their product greater than h/m.

Here’s the point: at room temperature, the thermal vibration of the atoms in anything to be teleported creates a sufficiently large X that V can be very small.

As for the engineering, I’m less concerned with the count of the particles that need to be entangled as to the fact that the values of many quantum states must be captured simultaneously for the teleportation to be effective. As I mentioned above, each measurement changes the system being measured. It would be inaccurate to claim that useful measurements cannot be made, but they would be tricky. In all likelihood, the sum of the X * V would be small enough for uncomplicated objects. For dynamic objects like the brain, where the state of the system could change while the measurements were being made, I doubt that what would be received would be identical to what was sent. I sure wouldn’t volunteer.
