Quantum Teleportation
You will see that teleporting the quantum state of an object A to object C requires a third
object B. B and C are created together as a quantum connected "EPR" pair. B then meets
A and transmits information about A backward-in-time to C. In addition, partial information about A is transmitted to C by an ordinary signal. The net teleportation effect is, therefore, a combination of ordinary retarded classical signal transmission forward in time together with an extraordinary advanced quantum transmission of information backward in time. A backward in
time effect at the quantum level has also been modeled by Henry P. Stapp in Physical Review A, July, 1994, p. 18.
