Quantum Entanglement in Future Communication Technologies

The arXiv blog on MIT Technology Review recently reported a breakthrough ‘Physicists Discover the Secret of Quantum Remote Control’ [1] which led some to comment on whether this could be used as an FTL communication channel. In order to appreciate the significance of the paper on Quantum Teleportation of Dynamics [2], one should note that it has already been determined that transfer of information via a quantum tangled pair occurs *at least* 10,000 times faster than the speed of light [3]. The next big communications breakthrough?
In what could turn out to be a major breakthrough for the advancement of long-distance communications in space exploration, several problems are resolved — where if a civilization is eventually established on a star system many light years away, for example, such as on one of the recently discovered Goldilocks Zone super-Earths in the Gliese 667C star system, then communications back to people on Earth may after all be… instantaneous.
However, implications do not just stop there either. As recently reported in The Register [5], researchers in Israel at the University of Jerusalem, have established that quantum tangling can be used to send data across both TIME AND SPACE [6]. Their recent paper entitled ‘Entanglement Between Photons that have Never Coexisted’ [7] describes how photon-to-photon entanglement can be used to connect with photons in their past/future, opening up an understanding into how one may be able to engineer technology to not just communicate instantaneously across space — but across space-time.
