I've started a couple of threads about this topic before, but those were a while ago, and I still have some nagging questions. 1.) If we wanted to quantum teleport something macroscopic, would scanning come into play? I thought that the whole point of QT was that you don't have to scan whatever it is you want to teleport. Would the only scanning take place before QT, in order to figure out the configurations and positions of the atoms so that a replica could be made at the destination (let's say the destination has stores of materials that they could use to make identical replicas)? Once the two objects are entangled, don't we just have to measure the quantum state of the object at the source and then send the result of the measurement to the destination? Wouldn't the entire object have one quantum state, as opposed to each atom having a state that must be measured? 2.) I understand that, in all of the experiments done so far in QT, the atoms were at close to absolute zero. For macroscopic objects to be quantum teleported, how low would the temperature have to be? Would you risk converting the object to a Bose-Einstein condensate, or in any other way fundamentally and irreversibly altering the object, by lowering it to a temperature suitable for QT? 3.) I once suggested that, if scanning was necessary, we could use nanobots that would infiltrate the object (if it was a human, they would go through the bloodstream and blood vessels), but was told that the energy required to scan all the atoms in such a short time frame would create a black hole. How so? 4.) This is kind of related to another thread I recently started, but if we wanted to entangle the two objects, would we have to entangle them atom-by-atom, or could we entangle the entire object? Would we have to keep the two objects close to each other and then send them apart?
