Scientists have recently been able to use quantum teleportation to transmit the quantum state of one atom to another atom as far as 90 miles away. From a quantum mechanical standpoint, this is the same as sending the atom itself, since two atoms with the same quantum state are indistinguishable. Could such a technique be used to transport a human being? I realize that there are concerns over decoherence, complexity, and scan time, but can't those be overcome with sufficiently advanced technology? It would appear that steps are being taken toward it. For example, just recently, UCSB physicists observed quantum mechanical behavior in a trillion-atom mechanical resonator. It shows that even macroscopic objects can be in a quantum state, right?
