Teleportation and Quantum Computing
Karl Hess · 2014
The stories about teleportation did sound to me like a horrible monster that was growing while walking through the cities. Everyone who knew that Walter and I were opposed to the idea of instantaneous influences at a distance told us that quantum teleportation was now proven and that it demonstrated clearly the existence of influences at a distance. My usual response was that quantum theory had some very great successes with predicting the precise energies of electrons in atoms. The experiments relating to quantum information such as the EPRB-type experiments and the so-called teleportation did not agreewith quantum theorywith such precision but only approximately. Furthermore, asmentioned, I soon convinced myself that the idea of quantum teleportation assumes that Bell is correct and influences at a distance do exist.We thus have another logical circle. Quantum teleportation is only then something remarkable if influences at a distance are assumed to exist on the basis of Bell’s work to start with. Experiments are explained using this assumption and then, because of a very approximate agreement of the experiments with the quantum predictions, it is claimed that teleportation has been proven. Here are the actual facts startingwith the concept of a quantum computer.
