I have a college-level understanding of Physics. A recent study from the University of Delft in the Netherlands that seems to suggest that quantum teleportation of information (as in "communication of information") is possible left me confused.
- Why can't quantum teleportation be used to transport information?
- Quantum entanglement as practical method of superluminal communication
and the answers in both threads suggest that one cannot use quantum teleportation for superluminal communication in the traditional/practical sense of the word.
Perhaps more interestingly, the university site (in dutch): http://www.tudelft.nl/nl/actueel/laatste-nieuws/artikel/detail/tu-delft-legt-fundament-voor-quantum-internet/ the statement ends with a quote from the authors saying:
"Ten tweede biedt teleportatie de mogelijkheid om informatie volledig veilig te versturen. Bij teleportatie reist de informatie niet door de tussenliggende ruimte en kan daarom niet worden afgeluisterd".
which can be translated as: "Secondly, teleportation offers the possibility to transmit information in a completely safe way. With teleportation the information does not travel through the space in between thus precluding eaves dropping."
Can these results be understood as a claim that superluminal communication (again, in the traditional/practical sense) is more feasible that previously believed?
