Japanese physicists performed calculations that prove that through quantum teleportation, energy can be transmitted to long distances. Quantum teleportation despite the name does not imply instant transfer to a distance, for it necessarily requires a classic (not superlight) channel communication. Nevertheless, the quantum state is transmitted in this case, and the concept of energy translation thus did not appear today, however, calculations showed that the possibility of such a transfer should quickly decrease with distance. Therefore, if sending atomic states realized for distances over 100 km, then with energy that Masahiro Hotta theory from 2008 years still allows you to teleport, it didn’t work. Teleportation of energy However, stop. Atom states are fine, but how can energy be transferred with their help? Mr. Hotta very inventive, and in his scheme Alice (particle A) by classic channel of communication transmits information to Bob (particle B) about that he needs to extract energy from the vacuum (on which is based experimentally confirmed Casimir effect). During experiment transmitted energy through the wire sip Idea Masahiro Hotta lies in the fact that since nearby points in quantum vacuum are quantum entangled, and Alice and Bob are close to each other friend, then Alice is able to measure “her” local field and use the results of these calculations to get information about Bob’s local field. If then this information will be Ambassador Bob through the classic communication channel, he will be able to use it for developing a strategy for extracting energy from your local field. In this case, the energy that he will get from the vacuum will always be less than the one Alice spent on the initial measurements. That is, thermodynamics remains in its right, and Alice can teleport energy to Bob in the form of data, which then allow him to extract energy from the vacuum. However the degree of quantum the entanglement between the local fields of Bob and Alice is rapidly declining with increasing distance between them. Bob can restore energy, spent by Alice is inversely proportional to the sixth power the distance between them, i.e. teleporting energy to any significant distance will require costs, comparable to planetary electricity generation per year. Now, Mr. Hotta and his colleagues at Tohoku University (Japan), seems to have found a workaround to solve this problem. They offer use compressed vacuum states. The latter are identical normal quantum states, except for one small detail: the area directly between Alice and Bob has an energy the density is much higher than in all other regions. Eventually quantum entanglement there can be maintained at much greater distance than in a normal situation. The question naturally arises: how such compressed states can be created in the laboratory for large distances? The authors believe that the quantum effect is useful here. Hall arising in thin wafers of semiconductors (preferably monatomic, such as phosphorene), which are affected by a strong magnetic field. Then the electrons in them flow unhindered into one direction along the edge of such a two-dimensional semiconductor sheet, which allows you to get the channel of quantum correlation, where it has place quantum entanglement – in general, with a squeezed state the vacuum seems to be clear. Mr. Hotta and his staff are just working on an experimental implementation of this scheme. But, emphasizes the scientist, for our species, his experiments will be pioneering. Earlier in the history of the universe when it was exposed rapid expansion almost immediately after the Big Bang (inflation), in it should have compressed vacuum states, followed by quantum teleportation, presumably significant amounts of energy. It might seem that Masahiro’s work Hotta, although important to theoretical quantum mechanics, is not too useful for the practical implementation of new electronics. Yes for creating quantum states will have to spend energy, and therefore it’s not yet very clear how practical (and energy-consuming) it will be quantum energy teleportation in quantum computers. But before how such teleportation will come true in an experiment, judge it very difficult, and therefore to sweep the practical threshold the potential of this type of energy transfer is not worth it now.
