Let's construct an argument against the possibility of teleportation using the Heisenberg uncertainty principle (sorry if this ruins anyone's fantasy. There are counterarguments to this). According to the uncertainty principle, once the position of a particle has been measured, there is an infinity of possibilities for the outcome of a momentum (velocity) measurement. If immediately after the position measurement we measure the momentum of the particle, we end up with a definite value for the momentum. Can we argue that now we know exactly both the position and momentum of the particle so that we can transmit this information to a remote receiver at the speed of light? If not, what does that tell us about the possibility of teleportation
