So if I were able to instantly recreate you at an atomic level on the otherside of the planet would you be OK with me obliterating the "redundant" you I started with?
The Heisenberg uncertainty principle says that nothing can be measured accurately. You can know location or speed but not both. In order to teleport ala star trek the precise location and speed of all sub atomic particles in the body must be measured then somehow converted to data, the body desintegrated and then re built at the new location. So the HUP prevents it!
but current quantum theory says no (as loosehead says), but there is no guarantee that this theory is really correct or not. right now it's very popular, but it may not be correct (many physicists think not).
Apparently, according to our present models, no. But the cool thing about science is that you never know when a new model will be developed that works better than previous models. We definitely don't know everything there is to know about matter. So my answer is maybe.
