http://www.tuhep.phys.tohoku.ac.jp/~hotta/extended-version-qet-review.pdf In the link above and by searching net with "Masahiro Hotta", anyone can find papers written by him on energy teleportation. As per Hotta, energy can certainly be transported from Point A to Point by entanglement and at the conclusion, he said that "it may be concluded that bipartite entanglement between A and B itself is not essential for QET" (QET: Quantum Energy Teleportation). His another conclusion is "this implies that an almost classical correlation between A and B is su¢ cient to execute QET for large separation, and is expected to be robust against environmental disturbances in contrast to the entanglement fragility in the previous quantum teleportation scheme. It should be emphasized, however, that this classical correlation is originally induced by the ground-state multipartite entanglement generated by nearest-neighbor interactions". I suggest to everybody to read papers published by Hotta in this regard and then make comments. But, after studying the paper, a scheme of information exchange suddenly come to my mind. As per the good old Alice and Bob analogy. As per Hotta, if Alice inject energy Ea to his own particle, the output Bob will get will be Eb, and the output is less than or equal to (maximum) the input by Alice. But, whatsoever, there is an output. I just want to propose that we can use this phenomenon for information exchange. As for example, when there is an input, there would be an output and that means 1(one). When there is no input (as per Hotta), there would be no output and that's 0(zero). I just wonder why don't we use this phenomenon for transfer of information. At present, conventional IT is enough for us to communicate. But, problems arise when we want to communicate with something that had already left our planet. As for example, some probe in Mars can send pictures and data far more quickly and clearly than conventional method and we don't have to set large antennas to capture the very faint signal sent by the probes. Moreover, such kind of communications will be much safer and "leakage proof". There is practically no chance for any third party to tap the data.
